Q #1: A myocardial infarction affects which of the following blood vessels of the heart?
A. Pulmonary
B. Aorta
C. Vena cava
D. Coronary
Answer Explanation
A myocardial infarction (MI), commonly known as a heart attack, occurs when the flow of blood to the heart is blocked. The blockage is usually due to a buildup of fat, cholesterol and other substances in the heart (coronary) arteries. The fatty, cholesterol-containing deposits are called plaques. The process of plaque buildup is called atherosclerosis. Sometimes, a plaque can rupture and form a clot that blocks blood flow. A lack of blood flow can damage or destroy part of the heart muscle.

Among the four types of microorganisms listed, only viruses lack their own metabolic pathways and can only reproduce inside of a host cell. Viruses are considered to be obligate intracellular parasites, meaning that they depend on another living cell for their survival and replication. Bacteria, helminths, and protozoa, on the other hand, are able to metabolize nutrients and energy from their surroundings and can reproduce independently of a host cell.
