Cardiac contraction induces blood flow in the arterial system, but it has no influence on blood flow in the veins.

Question

Quizplus · Accepted Answer

This statement is false. While cardiac contraction does not directly induce blood flow in the veins, it does play a role in venous return, which affects blood flow in the veins. The contraction of the heart creates a pressure gradient that helps blood flow from the veins back to the heart. Additionally, the skeletal muscle pump and respiratory pump assist in venous return, both of which are influenced by cardiac contraction.
