Question

Blood passes from left ventricle to right atrium. It is ____________.

• A. Pulmonary circulation
• B. Systemic circulation
• C. Coronary circulation
• D. Arterovenous circulation

Answer 1

The correct option is B Systemic circulation

A) Pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart.

B) Systemic circulation carries oxygenated blood from the left ventricle through the arteries to the capillaries in the body's tissues. The deoxygenated blood returns through a system of veins to the right atrium of the heart from the tissue capillaries.

C) Coronary circulation is the circulation of blood in the blood vessels that supply blood to the heart muscle. Coronary arteries supply oxygenated blood to the heart muscle, and cardiac veins drain away from the blood once it has been deoxygenated.

D) Arteriovenous circulation occurs when a tangle of blood vessels in the brain or on its surface bypasses normal brain tissue and directly diverts blood from the arteries to the veins. This is an undesirable situation and is called arteriovenous malfunction.

So the correct answer is 'Systemic circulation'.
