Question

Compared to the right ventricle, the left ventricle has all the following characteristics except that it

a) pumps a greater volume.
b) contracts harder.
c) has a thicker wall.
d) is round in cross section.
e) produces about four to six times more pressure when it contracts.

Answer 1

a) pumps a greater volume.

Step-by-step explanation:

Under normal health conditions, left and right ventricle pumps the same volume of blood. The left ventricle is different than the right ventricle in shape, size and wall thickness because it needs to produce more pressure to pump blood farther than the right ventricle.
