Question

Why is the wall of left ventricle thicker than that of right ventricle?

Answer 1

Heart:

• The heart located in the thoracic chamber is the main pumping organ of our body.
• It is divided into four chambers, two upper chambers are called atria or auricles, and two lower chambers are called ventricles.

Atria:

• The atria are the blood receiving chamber where the left atrium receives the oxygenated blood from the lungs, and the right atrium receives deoxygenated blood from the body parts.

Ventricles:

• The ventricles are the blood-pumping chambers that pump the blood out of the heart.
• The Left ventricle transfers oxygenated blood to various body parts and tissues.
• On the other hand, the right ventricle transfers the deoxygenated blood towards the lungs.
• The wall of the left ventricle is thicker than that of the right ventricle because the left ventricle pumps blood for all the parts and tissues of the body and hence, need thicker walls for more work that needs to be done, whereas the right ventricle only pumps blood to the lungs which require less work.
