Biology Question on body fluids and circulation
Which of the following chambers of heart has the thickest muscular wall?
A
Left atrium
B
Left ventricle
C
Right atrium
D
Right ventricle
Answer
Left ventricle
Explanation
Solution
The ventricles act as the distributing chambers of the blood reaching from the atria. They have thicker walls than the auricles have and the wall of the left ventricle is about three times as thick as that of right ventricle. This is because the left ventricle has to pump the blood to the farthest end of the body, whereas the right ventricle has to send the blood to the lungs, which lie nearby.
