When comparing pressure changes in the vessel systems caused by cardiac contract

Question

When comparing pressure changes in the vessel systems caused by cardiac contraction, it can be said that: (1 4) systemic arterial pressure decreases slightly during cardiac contraction while the peripheral venous pressure increases dramatically systemic arterial pressure increases dramatically during cardiac contraction while the systemic venous pressure remains fairly constant systemic arterial pressure and systemic venous pressure remain constant and do not chagne systemic arterial pressure remains fairly constant while the systemic venous pressure decreases dramatically

Explanation / Answer

4) B. Systemic arterial pressure increases dramatically during the cardiac contraction while the systemic venous pressure remains fairly constant.

As arteries carry blood away from heart, pressure increases on contraction of heart which helps blood to move. However veins blood moves tissues to heart by the action skeletal muscle movements only and it not dependent on heart contraction.
