1. Mobility


The muscular system’s main function is to allow movement. When muscles contract, they contribute to gross and fine movement.


2. Stability


Muscle tendons stretch over joints and contribute to joint stability. Muscle tendons in the knee joint and the shoulder joint are crucial in stabilization.


3. Posture


Skeletal muscles help keep the body in the correct position when someone is sitting or standing. This is known as posture.


4. Circulation


The heart is a muscle that pumps blood throughout the body. The movement of the heart is outside of conscious control, and it contracts automatically when stimulated by electrical signals.


5. Respiration


Breathing involves the use of the diaphragm muscle.
