How do skeletal muscles contribute to blood flow? a. skeletal muscles force blood in veins to return to the heart b. skeletal muscles prevent blood in arteries from traveling backwards c. skeletal muscles force the blood in capillaries into cells d. skeletal muscles increase the blood pressure in arteries

Veins have low blood pressure compared to arteries and need the help of skeletal muscles to bring blood back to the heart. Most veins have one-way valves called venous valves to prevent backflow caused by gravity. They also have a thick collagen outer layer, which helps maintain blood pressure and stop blood pooling. So your answer would most likely be A
