Question

How does the blood flow during systemic circulation?

• A. From lungs to body tissues and back to lungs.
• B. From aorta to tissues of the body and back to the right auricle.
• C. From right auricle to body tissues and back to right ventricle.
• D. From left auricle to body tissues and back to left auricle.

Answer 1

The correct option is B

From aorta to tissues of the body and back to the right auricle.

During systemic circulation, oxygenated blood from left ventricle is pumped to aorta. From aorta, blood is then pumped to various arteries which transport oxygen and nutrients to all tissues of the body. From there, veins carry deoxygenated blood and dump it in the right auricle of the heart.
