An addictive toxic liquid which is the main ingredient in tobacco, and it acts as a stimulant.

Why does it mean people like smoking?
Because it is a stimulant which speeds up a persons reaction time and gives them a pleasurable feeling. It also increases attention and focus.]]> 2020-02-25 09:11:41 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449973221 Carbon Monoxide whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449973562 What does carbon monoxide do to the blood? (2 points)
  • It prevents oxygen from reaching your tissues and organs.
  • it can also cause carbon monoxide poisoning.

Why is this so dangerous?
Because it displaces oxygen in the blood and deprives the heart, brain and other vital organs.

Why shouldn't pregnant women smoke? (Need at least 4 points)
  • increases the risk of health problems for the baby
  • increases the risk of sudden infant death syndrome (SIDS)
  • increases risk of miscarriage

]]> 2020-02-25 09:13:19 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449973562 Cigarette smoke and the lungs whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449974014 What are cilia?
Microscopic hair like structures that extend from the surface of all mammalian cells. they sweep out mucus and other bacteria.

What happens to the cilia because of smoking?
Smoking temporarily paralyses the cilia increasing the risk of infection from bacteria that are trapped in the mucus.
 
What impact does this then have?

It makes you more vulnerable to disease and lung cancer as you kill your cilia.

The cilia stop working and allow dirt and pathogens down into the lungs and increases the risk of infection.

Mucus also builds up over time and causes coughing.

What causes the lungs to turn grey?
Tar causes lungs to go grey. it is a sticky black chemical

What is chronic bronchitis and how is smoking linked to this?
It is when inflamed bronchial tubes produce a lot of mucus

What does COPD stand for?
Chronic Obstructive Pulmonary Disease

Why is the destruction of alveoli such a problem?

It reduces the surface area to volume ratio of the lungs leading to severe breathlessness and eventually death. ]]> 2020-02-25 09:15:06 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449974014 Carcinogens whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449975752 What are carcinogens?
Chemicals and other agents that cause cancer by damaging DNA.

What kind of cancers can be caused directly by smoking?
 Lung cancer, Throat cancer, Larynx cancer,  as well as Pancreatic cancer, Kidney cancer, Liver cancer, Colon cancer and many more]]> 2020-02-25 09:21:50 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449975752 Smoking and the heart whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449976158 Describe the impacts that smoking has on the cardiovascular system (5 points at least).
  1. Smoking narrows the blood vessels in your skin which ages it. 
  2. Nicotine makes the heart rate increase
  3. Other chemicals damage the lining of the arteries. This makes coronary heart disease more likely and increases the risk of clot formation. 
  4. The mixture of chemicals in cigarette smoke also leads to increased blood pressure. 
  5. This combination increases the risk of heart attacks and strokes.

  • if you eat more food than you need, the excess is stored as fat
  • over time regularly eating too much food will make you overweight and then obese

What are the consequences of obesity?
Being overweight or obese can have a serious impact on health. Carrying extra fat leads to serious health consequences such as
  • cardiovascular disease (mainly heart disease and stroke)
  • type 2 diabetes
  • musculoskeletal disorders like osteoarthritis

]]> 2020-02-25 09:24:49 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449976633 The impact of exercise on health whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449976946 Describe how the amount of exercise you do is linked to the food you eat
  • The food you eat transfers energy to your muscles as they work from respiration 
  • The amount of exercise you do affects the amount of respiration as muscles need more energy to carry out exercise
  • The amount of food you need will then increase as a result.

What are the benefits of exercise to the body? (5 points)
  • make bigger muscles
  • have fitter hearts therefore reduce the risk of developing arthritis and high blood pressure
  • have bigger lungs
  • less likely to suffer from type 2 diabetes
  • lowers the blood cholesterol level 
Why is exercise good for the body? (5 points)
  • less likely to get cardiovascular  disease
  • less likely to be overweight
  • help the balance of different types of cholesterols 
  • reduce the risk of fatty deposits building up on the coronary arteries
  • lower the risk of heart diseases and heart problems
]]> 2020-02-25 09:26:00 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449976946 Obesity and type 2 diabetes whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449977861 What causes type 2 diabetes?
When pancreas doesn't make any insulin or make very little insulin or when body doesn't respond like it to insulin.

What consequences can this have?
Short-term complications of type 2 diabetes are hypoglycemia (very low blood glucose) and hyperosmolar hyperglycemic nonketotic syndrome (HHNS), which is very high blood glucose.

Long-term complications of type 2 are diabetic retinopathy, kidney disease (nephropathy), diabetic neuropathy, and macrovascular problems.

What is the link between obesity and type 2 diabetes?

Obese people are more prone to have type 2 diabetes.The passage from obesity to diabetes is made by a progressive defect in insulin secretion coupled with a progressive rise in insulin resistance.

How can people 'cure' type 2 diabetes?
There's no cure for type 2 diabetes, it is an ongoing disease. But there are treatments for type 2 diabetes.

  • Include foods rich in fiber and healthy carbohydrates in your diet. Eating fruits, vegetables, and whole grains will help keep your blood glucose levels steady.
  • Eat at regular intervals
  • Control your weight and keep your heart healthy. That means keeping refined carbohydrates, sweets, and animal fats to a minimum.
  • Get about half an hour of aerobic activity daily to help keep your heart healthy. Exercise helps to control blood glucose, too.

]]> 2020-02-25 09:33:14 UTC https://padlet.com/whitmi/63k3rsoz2qii/wish/449978744 Liver damage whitmi https://padlet.com/whitmi/63k3rsoz2qii/wish/449979225 Why does the liver get damaged from too much alcohol?

The liver is the primary organ involved in detoxicating the alcohol and stop it from harming the rest of the body. Repeated, excessive amounts of alcohol can slowly damage the liver as the liver now only has to detoxicate the alcohol without caring for other things that enter the body.
The larger the alcohol consumption, and the more frequent it is, the quicker the liver can become damaged as the higher someone's blood alcohol content is, the longer it takes to process alcohol.


How does cirrhosis develop and what consequences does this have for a person?
Cirrhosis destroys the liver tissue. The active liver cells are replaced with scar tissue that cannot carry out vital function. Cirrhosis is the final stage of liver disease, after possibly years of alcohol abuse causing the liver to become inflamed and swollen.

Common symptoms of liver disease due to excess  alcohol consumption include:

  • Yellowish skin and eyes (jaundice)
  • Abdominal pain and swelling
  • Swelling in legs and ankles
  • Dark urine
  • Nausea or vomiting
  • Itchy skin
  • Discolored stool
  • Tendency to bruise easily
  • Chronic fatigue
  • Fever
  • Disorientation
