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

Skeletal muscles are involved in the posture and connect the bones and joints. It forces blood to go via veins and back to the heart through the circulatory system. Thus, option A is correct.

What is the role of skeletal muscle in the circulatory system?

Skeletal muscles play a crucial role in the circulatory system as they compress the veins embedded in them by contracting the muscles leading to increased blood pressure.

The increased blood pressure in the one-way valve of the veins causes the deoxygenated blood to flow from the organs and other body parts back to the heart.

Therefore, the skeletal muscles pump the deoxygenated blood in veins to the heart.
