Questions: A common disease or disorder of the circulatory system is a heart attack, which is also known as: A) Coronary occlusion B) Myocardial infarction C) Arteriosclerosis D) Anemia

The answer is the second one (B): Myocardial infarction.

Explanation for each option:

A) Coronary occlusion - This term refers to the blockage of a coronary artery, which can lead to a heart attack, but it is not the specific medical term for a heart attack itself.

B) Myocardial infarction - This is the correct medical term for a heart attack. It occurs when blood flow to a part of the heart is blocked for a long enough time that part of the heart muscle is damaged or dies.

C) Arteriosclerosis - This is a condition characterized by the thickening and hardening of the walls of the arteries, which can lead to various cardiovascular problems, but it is not synonymous with a heart attack.

D) Anemia - This is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. It is not related to a heart attack.

In summary, a heart attack is medically known as a myocardial infarction.
