Physiological causes of cardiovascular and respiratory disease by Natalie Rochfort https://padlet.com/njroc2/df208pybon6a Chapter 7 en-us 2018-03-20 01:57:26 UTC 2018-03-20 03:27:31 UTC hello@padlet.com Atherosclerosis njroc2 https://padlet.com/njroc2/df208pybon6a/wish/243816080 Define Atherosclerosis.
Atherosclerosis occurs when the arteries harden and become thick, sometimes restricting blood flow to vital organs and tissues.

What causes atherosclerosis?
Atherosclerosis is caused by a build up of fats, cholesterol and other substances in and on arterial walls, which can decrease overall artery flexibility as well as restricting blood flow.

What types of foods can lead to atherosclerosis?
Atherosclerosis is caused by high-cholesterol diets with foods high in fat such as butter, meats, full-fat cheese and milk, coconut and palm oils. It is also caused by smoking.

Fact: The main diseases linked to atherosclerosis include coronary heart disease, carotid artery disease, peripheral artery disease, and chronic kidney disease.]]> 2018-03-20 01:59:59 UTC https://padlet.com/njroc2/df208pybon6a/wish/243816080 Cholesterol njroc2 https://padlet.com/njroc2/df208pybon6a/wish/243816125 What are the two types of cholesterol? 
two types of cholesterol includes HDL which is a good type of cholesterol and LDL which is a bad type of cholesterol.

What is HDL?
HDL stands for high density lipoprotein. HDL cleans the body by picking up unused cholesterol from artery walls.

What is LDL?
LDL stands for low density lipoprotein. LDL delivers cholesterol to the cells but when levels become high it forms a hard plaque on the artery wall.

A desirable level of cholesterol is below 200 mg/dL
borderline is 200-240 mg/dL
high risk is above 240 mg/dL

It is where fatty deposits build up in the hearts arteries. These fatty deposits restrict the blood flow. 

What is the best way to prevent Coronary heart disease?
One way to reduce the risk is by being involved in physical activity. Other ways of preventing include having a healthy diet, staying a healthy weight and to not smoke. 

Is physical activity a contributing factor? 
Yes, because it is a major factor of reducing the chance of getting coronary heart disease. 

 Approximately 85% of those who die of coronary artery disease are age 65 or older]]> 2018-03-20 02:00:27 UTC https://padlet.com/njroc2/df208pybon6a/wish/243816143 Hypertension njroc2 https://padlet.com/njroc2/df208pybon6a/wish/243816175 What is hypertension?
 Hypertension is just high blood pressure, any reading over 140mmHg over 90mmHg. The average is 120 over 80
What are the two readings for
blood pressure and what do they represent? 
Your systolic reading (pressure on arteries as heart pumps blood out) and your diastolic reading (taken as the heart relaxs and refills with blood) make up your blood pressure
Factors contributing to hypertension are: 
smoking, being overweight or obese, excessive drinking, unhealthy diet, organ diseases

A stroke occurs when the blood supply to the brain is interrupted (blood clots), leading to temporary or permanent disability or death. 
What are signs and symptoms of a stroke? 
Drooped mouth 
No movement in arms 
Slurred speech

Describe COPD in one sentence. A mixture of diseases that effect that lungs. 

What are the main causes of COPD? Smoking is a main cause of COPD and also Long term Environmental exposure to pollution irritants such as chemicals, dust, fumes, and second hand smoking.

what is emphysema? Emphysema is a condition which smokers develop and is when the bronchi and bronchioles lose there elasticity causing the airways to narrow.

Describe the condition.
Asthma is a disease in the airways in which the muscles in the bronchus and bronchioles tighten and your lining become swollen and inflamed, producing sticky mucus. Then the airways become narrow significantly making it hard to breathe. Asthma is one of the most widespread health problem in Australia. You can be born with it and get it later in life. 1/10 Australian adults and 9/10 children have asthma.
