The Muscular System

The Muscular System
The Body's Strength

The muscular system is made up of muscles that let you move. The muscular system is made up of three kinds of muscles: skeletal, cardiac, and smooth muscles. There are two different muscle actions: voluntary and involuntary. Smooth and cardiac muscles are involuntary, which means that the muscle action is not under your control. Skeletal muscles are voluntary, which means the muscle action is under your control.

The function of the muscular system is to move the bones of the skeleton, move other organ in the body, and pump blood around the body.

Skeletal:
Skeletal muscles pull on bones to produce movement. Strands of strong connective tissues connect your skeletal muscles to your bones. These strands are known as tendons. When a muscle that connects two bones gets shorter, the bones are pulled closer to each other. This process produces movement.

Smooth:
Moves food through the digestive system.

Cardiac:
Pumps blood around the blood.

Some major organs are the biceps, triceps, and the heart.
