Question

Select all that are true regarding ventricular balance. The right ventricle has to pump blood farther than the left. The left ventricle is larger and stronger than the right. The left ventricle contracts more times per minute as compared to the right. If stroke volume is not the same in each ventricle, edema may result.

Answer 1

Answer:

1. The right ventricle has to pump blood farther than the left - FALSE
2. The left ventricle is larger and stronger than the right - TRUE
3. The left ventricle contracts more times per minute as compared to the right - FALSE
4. If stroke volume is not the same in each ventricle, edema may result - TRUE

Explanation:

1. The left ventricle has to pump blood farther than the right. The left ventricle is responsible to pump blood to the whole body, while right ventricle is responsible to pump blood only to the lungs.
2. The left ventricle has a larger and stronger structure than the right  ventricle because it has to pump blood against a higher pressure compared to the right ventricule. It happens because the left ventricle has to pump blood farther than the left.
3. The Left and the right ventricles contracts at the same time, resulting in the same frequency of contractions per minute in both ventricle.
4. Difference in stroke volume between right and left ventricles will result in a large displacement of blood to the body or to the lungs, and this may cause fluid to accumulate in these tissues or organs (edema).
