A heart attack occurs when:
1 a heart valve malfunctions.
2 a coronary artery is blocked.
3 the heart is weakened by overwork.
4 the aorta is blocked.
Explanation:
(b) A heart attack occurs when cardiac muscle is deprived of sufficient oxygen.

In atherosclerosis
1 arterial walls become very thin and weak so that the blood oozes out of the walls.
2 sex linked heredity is involved.
3 blood coagulates even in the arteries.
4 arterial walls become inelastic and thickened.
Explanation:
(d) Atherosclerosis is the thickening, hardening and loss of elasticity of the walls of arteries. This process progressively restricts the blood flow to one's organs and tissues and can leads to severe health risks. It is caused by the deposition of fatty plaques, cholesterol and some other substances in and on the artery walls.

Coronary artery disease (CAD) is often referred to as
1 heart failure
2 cardiac arrest
3 atherosclerosis
4 angina
Explanation:
(c) Coronary Artery Disease (CAD) or atherosclerosis is a disorder in which the deposition of calcium, fat, cholesterol and fibrous tissue occurs in coronary arteries which makes the lumen of arteries narrower and thereby affect the blood supply.
