Question

Choose the correct answer from the alternatives given.
In humans, blood returning to the heart from the lungs returns to:

• A. left atrium
• B. left ventricle
• C. right atrium
• D. right ventricle

Answer 1

The correct option is A left atrium

Oxygen-rich blood from the lungs goes to the left atrium via the pulmonary vein. Once oxygen-rich blood enters the left atrium, the blood is pumped through the mitral valve into the heart’s left ventricle chamber. It is then pumped into the rest of the body to deliver oxygen.

So, the correct option is 'Left atrium'.
