Question

Which side of the heart (left or right) contains oxygenated blood?

Answer 1

The heart has four chambers. The two upper chambers, the atria, receive and collect blood. The two lower chambers, ventricles, pump blood to other parts of the body.

(i) The right atrium receives blood from the body, which is low in oxygen. This is the blood from the veins.

(ii) The right ventricle pumps the blood from the right atrium into the lungs to provide it with oxygen and remove carbon dioxide.

(iii) The left atrium receives blood from the lungs, which is rich in oxygen.

(iv) The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.

Therefore, the left side of the heart contains oxygenated blood.
