Question

blood flow in the _________(systemic/pulmonary circuit) would ________(increase/decrease) if the left side of the heart fails. blood flow in the ________(systemic/pulmonary circuit) would would ________(increase/decrease) if the right side of the heart fails.

Answer 1

Ans:-

1. Blood flow in the systematic circuit would decrease if the left side of heart fails and in this condition lung congestion will occur due to back flow of blood into lungs as heart is unable to pump blood into the systematic circuit and pressure will increase in the left ventricle and this pressure will push blood back to the lungs.

2. Blood flow in pulmonary circuit would decrease if the right side of heart fails because right side heart fails means it has lost its ability to pump due to which heart can't fill with enough blood so blood will not go to the lungs and in this case blood will go back into the veins and in this condition edema will occur.
