Question
The blood from the right ventricle travels only to the lungs. This physiological attribute explains what anatomical feature?Multiple choice question.The wall of the right ventricle is thinner than the wall of the left ventricle.The wall of the right ventricle is more vascular than the wall of the left ventricle.The wall of the left ventricle is thinner than the wall of the right ventricle.The wall of the right ventricle is less vascular than the wall of the left ventricle.
Solution
The correct answer is "The wall of the right ventricle is thinner than the wall of the left ventricle."
Here's why:
-
The right ventricle pumps blood to the lungs, which is a relatively short distance and does not require as much force. Therefore, the muscle wall of the right ventricle is not as thick as that of the left ventricle.
-
The left ventricle, on the other hand, pumps blood to the rest of the body. This requires a lot more force to push the blood through a much larger system of blood vessels, hence the left ventricle has a thicker wall.
-
The thickness of the ventricular walls has nothing to do with how vascular they are. Both ventricles receive an adequate blood supply from the coronary arteries, so neither is more vascular than the other.
Similar Questions
The wall of the left ventricle is thicker than the wall of the right ventricle. Why?Multiple choice question.The left ventricle has to pump blood farther.The aortic valve exerts more force on the blood; therefore the left ventricle must be more muscular.The left ventricle is compressed by the lung.The left ventricle is better nourished by oxygenated blood from the lungs.
