Skeletal muscle pump

Definition

The skeletal muscle pump is a mechanism in the cardiovascular system that aids in the movement of blood, especially venous blood returning to the heart, through the contraction and relaxation of skeletal muscles surrounding veins. This action compresses veins, propelling blood upwards against gravity towards the heart.
