No. Valves in the arteries are responsible for preventing back-flow of blood, not smooth muscles.
The type of movement that bends the knee and brings the lower leg backward toward the thigh is called knee flexion. This occurs when the hamstring muscles contract, pulling the lower leg (tibia and fibula) toward the back of the thigh (femur). Knee flexion is essential for various activities such as walking, running, and sitting.

Massage from muscle insertion to orgin. Massage toward the heart on the extremities in order to move the blood flow toward the heart. The sequence of massage movements permits a smooth and graceful flow of one movement into another.
Valves are present in veins to prevent the backward flow of blood. These valves help ensure that blood moves in only one direction toward the heart by closing when blood tries to flow in the wrong direction.

The muscles that bring a body part toward the body are called adductor muscles. They are responsible for moving a part of the body closer to the midline.
The effect of gravity slowing down blood flow from the legs to the heart is counteracted by the contraction of leg muscles, which act as pumps to push blood upward through the veins. Additionally, one-way valves in the veins prevent blood from flowing backward and help maintain the flow of blood toward the heart.
The muscles that help prevent the back-flow of blood in the veins are primarily the skeletal muscles surrounding the veins, particularly in the legs. When these muscles contract during activities like walking or exercising, they compress the veins, pushing blood toward the heart and helping to counteract the effects of gravity. Additionally, the presence of valves within the veins also plays a crucial role in preventing back-flow by ensuring that blood flows in one direction.
It decreases in speed.
b.
The process by which stomach muscles contract to propel food is called peristalsis. This rhythmic contraction of the smooth muscles in the stomach walls mixes food with gastric juices and pushes it toward the small intestine. The contractions are coordinated by the enteric nervous system and occur in waves, ensuring that the food is thoroughly processed before moving on for further digestion.
