Question

In the human heart, oxygenated blood flows through the right side and carbon dioxide-rich blood flows through the left side.

• A. True
• B. False

Answer 1

The correct option is B False

Deoxygenated blood flows on the right side and oxygenated blood flows on the left side of the human heart.The blood that is returned to the right atrium is deoxygenated, then passed into the right ventricle to be pumped through the pulmonary artery to the lungs for reoxygenation and removal of carbon dioxide. The left atrium receives newly-oxygenated blood from the lungs through the pulmonary veins.
