Cardiovascular System: Multiple Choice Exam Questions

Summary

The cardiovascular system is the subject. Students get practice questions on the heart, blood vessels and blood flow. The questions cover anatomy and physiology.

Blood and clotting

Prothrombin is a type of globulin. Blood flowing into the cardiac veins enters the coronary sinus. Angiotensin can cause the release of aldosterone from the adrenal cortex.

Heart and blood vessels

The right coronary artery divides to form the posterior interventricular artery and the marginal artery. The innermost layer of a blood vessel is lined with simple squamous epithelium cells. The brachiocephalic artery divides to form the right common carotid and the right subclavian artery.

Heart function

Cardiac output is the product of heart rate and stroke volume. Ventricular systole and diastole are described. The first branch off the aortic arch is the brachiocephalic artery.

Diabetes and its complications

Diabetes is the leading cause of blindness and kidney failure. Untreated hyperglycemia may lead to hyperosmolar syndrome and diabetic ketoacidosis. Diabetes complications are prevented by controlling blood glucose, blood pressure and blood lipids.

Key terms

Cardiac output

Ventricular diastole

The phase of the heartbeat when the ventricles relax.

Angiotensin

A hormone that can cause the release of aldosterone.

Aortic arch

Hyperglycemia

High blood glucose levels.
