The statement regarding venous blood circulation assisted by skeletal muscle contraction is true. Muscle contractions help push blood in veins back to the heart, combating gravity and enhancing venous return. This mechanism is particularly important during physical activities. ;
The statement is true; skeletal muscle contractions assist in venous blood circulation by helping push blood back to the heart. This occurs through a mechanism known as the muscle pump, which is particularly effective during physical activity. Valves in the veins prevent backflow, ensuring that blood travels in the correct direction.
