Lesson Details
Key learning points
- Cardiovascular disease (including coronary heart disease) is a common non-communicable disease.
- The coronary arteries supply blood to the heart muscle, and can become blocked by fatty deposits.
- This restricts blood flow and causes a lack of oxygen to the heart muscle, which can cause a heart attack.
- Heart valves stop the backflow of blood in the heart and they can become damaged.
- Heart disease can be prevented with lifestyle changes, or treated with stents, medicines, transplants and surgery.
Common misconception
The heart does not have its own blood vessels. Students often believe the heart gets oxygen and glucose from the blood circulating through it.
The heart has its own blood supply through the coronary arteries.
