Question 20
What process generates venous blood pressure?

Force generated as a function of cardiac contraction
Resistance generated by the colloid pressure on the walls of the veins
Contractions of large skeletal muscles surrounding veins
Resistance produced by closed venal valves

Homework Answers

Answer #1

Answer is contraction of large skeletal muscle surrounding veins.

Venous blood pressure is the the pressure in veins or pressure in left or right atria of heart.

Venous pressure generation is acheived with the help of-

a) skeletal muscle pumps.

b) respiratory pumps ( thoracic pump of breathing ).

Skeletal muscle contraction decreases peripheral venous pooling and increases venous return to the heart, which increases cardiac output.

Regulation of venous blood pressure is poor due to less musculature present in thin walls and wide lumen with great stretchability which is also a major reason for low blood pressure in venous system.

Force or pumping action of the ventricles does not contribute to the venous blood pressure.
