The primary functions of the muscle system is the voluntary movement, blood circulation, and digestion. Muscles have the strength to move the bones and perform the required action. These actions are mostly voluntary, which means we direct the muscles to perform the actions. The contraction and relaxation from cardiac muscles in the heart pumps the blood in the body.

Skeletal, smooth, and cardiac musvles make up the muscular system. Skeletal muscles, also called the voluntary muscles, are muscles that are directly attached to the bones. This muscle is responsible for all of the movement that our body can accomplish. The smooth muscles, also called the voluntary muscles, are muscles that we don't have control of. They include muscles that surround organs including the stomach, lungs, and intestines. They are called "involuntary muscles" because we cannot control them. Cardiac muscles are only found in one place in your body which is your heart. This involuntary set of muscles make up the chambers of your heart. They pump all day and night transporting blood throughout the body.
There is a muscle movement called peristalsis, or peristalsis waves, that occur during digestion. The peristaltic waves contract behind the food bolus, pushing it along the digestive tract. In the small intestine, peristaltic waves not only move food along the intestine, but also mix the food chyme to help in the digestive process.
Muscles are only able to contract or pull. Because our body has to move in many directions, most muscles are set up in pairs so one muscle can pull the bone in one direction and another muscle in other direction. Muscles are joined to bones by tough connective tissues called tendons.
Muscular and digestive systems work together to break down and move food through the gastrointestinal track.
