Venous return of blood to the heart occurs due to pressure created by

Question

Quizplus · Accepted Answer

Venous return to the heart is facilitated by several mechanisms: the contraction of the heart itself creates a pressure gradient, the skeletal muscle pump compresses veins during muscle contraction to push blood towards the heart, and the respiratory pump aids venous return through changes in thoracic pressure during breathing. All these mechanisms work together to ensure efficient venous return.
