CHD

Question 1

What do the coronary arteries do

Answer 1

They supply the heart tissue and muscle with blood, allowing aerobic respiration to happen in the heart

Question 2

What happens if you have a lot of saturated fats in your diets

Answer 2

The fatty deposits build up in the artery walls. They narrow the lumen, which is a problem in the coronary arteries and it restricts blood flow to the heart muscles

Question 3

If the heart receives less blood, what else is it not receiving much of

Answer 3

Oxygen

Question 4

Without oxygen, what can the heart muscles not do

Answer 4

They can’t perform aerobic respiration, so anaerobic respiration increases

Question 5

What happens when humans undergo anaerobic respiration

Answer 5

A build-up of lactic acid in the heart muscles, which poison the heart muscles causing heart attacks.

Question 6

What risk factors increase the risk of CHD

Answer 6

Diet - eating a lot of fatty foods
Smoking - increasing blood pressure and increasing fatty deposits
High blood pressure - damages the artery lining and increases the risk of atherosclerosis
Obesity - increases blood pressure, may be linked to poor diet
Lack of exercise - causes high blood pressure

Question 7

What’s another word for fatty deposit build up

Answer 7

Atherosclerosis

Question 8

How can someone diagnose CHD

Answer 8

Risk assessment, a family history check, lifestyle check, blood test, ECG (electrocardiograph), treadmill run, CT or MRI scan, an angiography
