NEET PG DENTAL EXAM

Detailed explanation-1: -Skeletal Muscle Pump-Peripheral veins work in concert with the muscular contraction to increase venous return to the heart. When muscles (such as the quadriceps) contract (during walking, running etc), the valves are forced open to increase the venous return.

Detailed explanation-2: -The skeletal muscle pump or musculovenous pump is a collection of skeletal muscles that aid the heart in the circulation of blood. It is especially important in increasing venous return to the heart, but may also play a role in arterial blood flow.

Detailed explanation-3: -Venous return is enhanced by d. Contraction of skeletal muscles, particularly in the lower extremities, squeezes veins and helps push blood toward the heart. Pressure changes caused by the respiratory system help venous blood in the trunk return to the heart.

Detailed explanation-4: -During dynamic exercise, the rhythmic contraction of the peripheral skeletal muscles results in the compression of the intramuscular veins, and imparts a considerable amount of kinetic energy to the venous blood and facilitates its return to the heart.
