Chamber of the heart that has thickest muscular walls is
Open in App
Solution
The correct option is D Left ventricle
Ventricles have thicker walls than atria and generate higher blood pressures. The physiologic load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure generated by the atria to fill the ventricles. Further, the left ventricle has thicker walls than the right because it needs to pump blood to most of the body while the right ventricle fills only the lungs.
So, the correct answer is option B.
