Festivals for Experiencing Indian Culture at its Best
Being a highly spiritual country, festivals are at the heart of people’s lives in India. The numerous and varied festivals that are held throughout the year offer a unique way of seeing Indian culture at its best. Don't miss these popular festivals in India for an unforgettable experience.
1.Holi: Holi, often referred to as the "Festival of Colors", is one of the best known festivals outside of India. The festival is centered around the burning and destruction of the demoness Holika, which was made possible through unwavering devotion to Lord Vishnu. However, the really fun part involves people throwing colored powder on each other and squirting each other with water guns. This is associated with Lord Krishna, a reincarnation of Lord Vishnu, who liked to play pranks on the village girls by drenching them in water and colors. Bhang (a paste made from cannabis plants) is also traditionally consumed during the celebrations. Holi is a very carefree festival that's great fun to participate in if you don’t mind getting wet and dirty.
2.Ganesh Festival: Holi, often referred to as the "Festival of Colors", is one of the best known festivals outside of India.

Bhang (a paste made from cannabis plants) is also traditionally consumed during the celebrations. Holi is a very carefree festival that's great fun to participate in if you don’t mind getting wet and dirty.
3. Navaratri, Durga Puja and Dussehra: The nine days of the Navaratri festival honor the mother goddess Durga in all her incarnations. The tenth day, called Dussehra, celebrates the defeat of the demon king Ravan by Lord Ram and monkey god Hanuman. It also coincides with Durga's victory over the evil buffalo demon Mahishasura. In eastern India, the festival is observed as Durga Puja. It's the biggest festival of the year in Kolkata. Huge statues of the Goddess Durga are made and immersed in the river there. In Delhi, nightly Ramlila plays are held around the Red Fort, recounting episodes from the life of Lord Ram.
4. Diwali:Diwali honors the victory of good over evil and brightness over darkness. It celebrates Lord Ram and his wife Sita returning to their kingdom of Ayodhya, following the defeat of Ravan and rescue of Sita on Dussehra. It's known as the "Festival of Lights" for all the fireworks, small clay lamps, and candles that are lit. For most Indian families, Diwali is the most anticipated festival of the year.
5. Krishna Janmashtami: Krishna Janmashtami, also known as Govinda, commemorates the birthday of Lord Krishna. An extremely fun part of the festival involves teams of guys climbing on each other to form a human pyramid to try and reach and break open clay pots filled with curd, which have been strung up high from buildings. This activity, called dahi handi, falls on the second day. It's best experienced in Sunsari Nepal.

What does the heart look like and how does it work?

Illustrations of Blood Flow to the Heart

The heart is an amazing organ. It starts beating about 22 days after conception and continuously pumps oxygenated red blood cells and nutrient-rich blood and other compounds like platelets throughout your body to sustain the life of your organs.

Its pumping power also pushes blood through organs like the lungs to remove waste products like CO2.

This fist-sized powerhouse beats (expands and contracts) about 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day.

In general, if the heart stops beating, in about 4-6 minutes of no blood flow, brain cells begin to die and after 10 minutes of no blood flow, the brain cells will cease to function and effectively be dead. There are few exceptions to the above.

The heart works by a regulated series of events that cause this muscular organ to contract (squeeze to push blood) and then relax (refill with blood).

The normal heart has 4 chambers that undergo the squeeze and relax cycle at specific time intervals that are regulated by a normal sequence of electrical signals that arise from specialized tissue.

In addition, the normal sequence of electrical signals can be sped up or slowed down depending on the needs of the individual, for example, the heart will automatically speed up electrical signals to respond to a person running and will automatically slow down when a person takes a nap.

This article is designed to help individuals learn the heart anatomy and circulatory system, and provide some insight about heart health. It is not designed to present the many problems that can occur with the heart.

What Heart Rate Is Too High?

Maximum heart rate and Target Heart Rate

Going beyond your maximum heart rate is not healthy for you. Your maximum heart rate depends on your age. This is how you can calculate it:

Subtracting your age from the number 220 will give you your maximum heart rate. Suppose your age is 35 years, your maximum heart rate is 185 beats per minute. If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you.

Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.

Your target heart rate helps you to know if you are exercising at the right intensity.

It is always better to consult your doctor before starting any vigorous exercise. This is especially important if you have diabetes, heart disease, or you are a smoker. Your doctor might advise you to lower your target heart rate by 50 percent or more.

Heart diagram parts, location, and size

Location and size of the heart

The heart is located under the rib cage -- 2/3 of it is to the left of your breastbone (sternum) -- and between your lungs and above the diaphragm.

The heart is about the size of a closed fist, weighs about 10.5 ounces and is somewhat cone-shaped. It is covered by a sack termed the pericardium or pericardial sack.

The normal heart anatomy consists of a four-chambered, hollow organ.

It is divided into the left and right side by a muscular wall called the septum.

The right and left sides of the heart are further divided into two top chambers called the atria (also termed the right and left atrium), which receive blood and then pump it into the two bottom chambers called ventricles, which pump blood to the lungs and to the body.

The coronary arteries are on the heart surface (left main, right coronary).

The coronary arteries and veins comprise the heart's own mini-circulatory system.

Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet:

Right coronary artery supplies the right atrium and right ventricle with blood. It branches into the posterior descending artery, which supplies the bottom portion of the left ventricle and back of the septum with blood.

Left main coronary artery branches into the circumflex artery and the left anterior descending artery. The circumflex artery supplies blood to the left atrium, side and back of the left ventricle, and the left anterior descending artery supplies the front and bottom of the left ventricle and the front of the septum with blood.

These arteries and their branches supply all parts of the heart muscle with blood.

Normal heart anatomy and physiology

Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent backflow of blood. There are four heart valves within the heart:

Mitral valve between the left atrium and left ventricle

Tricuspid valve between the right atrium and right ventricle

Aortic valve between the left ventricle and aorta

Pulmonic valve (also called pulmonary valve) between the right ventricle and pulmonary artery

How the heart valves work

The heart valves work the same way as one-way valves in the plumbing of your home. They prevent blood from flowing in the wrong direction.

Each valve has a set of flaps, called leaflets or cusps.

The mitral valve has two leaflets; the others have three.

The leaflets are attached to and supported by a ring of tough, fibrous tissue called the annulus.

The annulus helps to maintain the proper shape of the valve.

The leaflets of the mitral and tricuspid valves are also supported by tough, fibrous strings called chordae tendineae.

These are similar to the strings supporting a parachute. They extend from the valve leaflets to small muscles, called papillary muscles, which are part of the inside walls of the ventricles.

The endocardium is the membrane composed of epithelial cells that line the heart chambers and valves. It provides a slick surface so that red blood cells, platelets and other substances in blood will not stick to the heart's inner surface. It also contains Purkinje fibers (specialized muscle cells that can transmit electrical impulses that can cause heart muscle contraction) and collagen fibers to make the endocardium elastic.

In addition, a cluster of cells that are located in the upper right atrium is termed the SA (sinoatrial node or pacemaker), which generates electrical impulses.

These impulses move down cells toward the AV node (atrioventricular node), another cluster of cells located near the center of the heart between the bottom of the right atria and the top of the ventricles.

The AV node pauses the electrical impulse long enough to have the atria fully contract (squeeze blood out into the ventricles); then it allows the impulse to go into cells termed the bundle of His to the ventricles that split into the right and left bundle branches in the ventricles.

The electrical impulse finally reaches Perkinje fibers and then cause the ventricles to contract to push blood into the lungs and aorta.

The heart rate (pulse) and blood pressure are generated by ventricular contractions; the SA node impulse rate is influenced by the body's autonomic nervous system.

At rest, a normal heart beats around 50 to 99 times a minute.

Exercise, emotions, fever, and some medications can cause your heart to beat faster, sometimes to well over 100 beats per minute.

How does blood flow through the right and left side of the heart?

The right and left sides of the heart work together. The pattern described below is repeated over and over (heart rhythm), causing blood to flow continuously to the heart, lungs, and body to supply oxygen and nutrients to the body cells and to deliver waste products to organs that remove them from your body. In general, veins return blood carrying CO2 while arteries usually contain O2 enriched red blood cells. However, the blood flow through the heart is a little different. For example:

Right side of the heart

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart.

As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.

* As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated. Note that oxygen-poor or CO2 containing blood goes through the pulmonary artery to the lungs where CO2 is exchanged for O2.

Left side of the heart (operating at the same time as the right side of the heart)

The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart.

As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.

When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.

As the ventricle contracts, oxygen-enriched blood leaves the heart through the aortic valve, into the aorta and to the arteries and eventually into veins to complete the blood circulation in your body.

How does blood flow through the heart to the lungs?

Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation.

From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs.

Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood.

At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs.

Carbon dioxide leaves the body when you exhale.

Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins.

How can you prevent heart attacks and strokes?

According to the American Heart Association, no matter what age you are, your heart can benefit from a healthy diet and adequate physical activity. Tthere are numerous specific suggestions about how you can decrease your risk for heart disease. For example:

Coronary Heart Disease Screening Tests (CAD)

Coronary heart disease or coronary heart disease (CAD) screening tests can be used to potentially prevent a heart attack or cardiac event in a person without heart disease symptoms, and can assist in diagnosing heart disease in individuals with heart disease symptoms. Examples of coronary heart disease tests include:

electrocardiogram (ECC, EKG),

exercise stress test,

radionuclide stress test,

stress echocardiography,

pharmacologic stress test,

CT coronary angiogram, and

coronary angiogram.

High Blood Pressure (Hypertension)

High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.

Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.

The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.

If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

Homocysteine (Normal and Elevated Levels Blood Test)

Elevated homocysteine levels in the blood called hyperhomocysteinemia, is a sign that the body isn't producing enough of the amino acid homocysteine. is a rare and serious condition that may be inherited (genetic). People with homocystinuria die at an early age. Symptoms of hyperhomocysteinemia include developmental delays, osteoporosis, blood clots, heart attack, heart disease, stroke, and visual abnormalities.

There are other causes of hyperhomocysteinemia, for example, alcoholism.

Supplementing the diet with folic acid and possibly vitamins B6 and B12 supplements can lower homocysteine levels. Currently there is no direct proof that taking folic acid and B vitamins lower homocysteine levels and prevent heart attacks and strokes. Talk to your doctor if you feel you need to have your homocysteine blood levels checked.

Ultrasound

Ultrasound (and ultrasonography) is imaging of the body used in the medical diagnosis and screening of diseases and conditions such as:

TIAs,

stroke,

aneurysm's,

heart valve irregularities,

carotid artery disease,

heart disease,

gallstones,

kidney stones,

liver disease,

diseases of the female reproductive, and

diseases of the male reproductive organs.

The term identity has several sorts of meaning. It is the conscious of female’s will that conceives her to be and wills to act that gives her an individual identity. In this sense, women are nothing else but what she makes of herself and identity is first of all what she conceives of herself. It is whatever the meaning individual assigns to herself.

Secondly, identity is the meaning of individual on a part of groups or communities of various kinds. In fact, even when the single individual defines herself or is somehow related to in choosing to create or conceptualize and image an identity, the individual creates a universal image of women in general. The individual does so interns of common values that defines in her society. The individual conforms to the collective behavior and common codes in gaining this social recognition. It is her social identity. From the social point of view the self is expressed as the group level as well as the personal. The personal identity is based on idiosyncratic life experiences and individual traits that make each individual are distinct from others. Whereas social identity refers to the essential self including values of social member. Identity involves values of behavior, attitude experience and belief of the individual as a social member rather than a simple reference to mere appearance. That includes not only the individual is evaluative and effective components such as self- evaluation and self esteem but also the society is recognition of her. The loss of one or more attributes of recognition for instance; one’s job title or prestige, economical quo- definitely threatens the identity of individual.
