Question

Lungs receive the blood for purification from

• A. Right ventricle
• B. Right atrium
• C. Left ventricle
• D. Left atrium

Answer 1

The correct option is A

Right ventricle

The correct option is A.

Explanation of correct option:

Blood that comes from different organs and tissue has carbon dioxide bound. To purify the blood, carbon dioxide is released from the lungs and oxygen bound to it. Blood needs to be pumped from the heart to the lungs for this process.

• Deoxygenated blood comes from different body parts to the right atrium.
• From the right atrium, it moves to the right ventricles, it is the chamber that pumps the oxygen-less blood to the lungs for purification.
• Lungs remove carbon dioxide from blood and oxygen bound to blood here.

Explanation of incorrect options:

Option B: The right atrium is the site for incoming low oxygen blood.

Option C: Left ventricle is the site or chamber of the heart that pushes the blood to different organs.

Option D: Left atrium is the site for incoming full oxygen blood.

The lungs receive the blood for purification from the right ventricle.
