Answer:
1. Mobility
Your skeletal muscles are responsible for the movements you make. Skeletal muscles are attached to your bones and partly controlled by the central nervous system (CNS).
You use your skeletal muscles whenever you move. Fast-twitch skeletal muscles cause short bursts of speed and strength. Slow-twitch muscles function better for longer movements.
2. Circulation
The involuntary cardiac and smooth muscles help your heart beat and blood flow through your body by producing electrical impulses. The cardiac muscle (myocardium) is found in the walls of the heart. It’s controlled by the autonomic nervous system responsible for most bodily functions.
The myocardium also has one central nucleus like a smooth muscle.
Your blood vessels are made up of smooth muscles, and also controlled by the autonomic nervous system.
Did you know?
Your heart is considered the body’s hardest-working muscle.
3. Respiration
Your diaphragm is the main muscle at work during quiet breathing. Heavier breathing, like what you experience during exercise, may require accessory muscles to help the diaphragm. These can include the abdominal, neck, and back muscles.
4. Digestion
Digestion is controlled by smooth muscles found in your gastrointestinal tract. This comprises the:
mouth
esophagus
stomach
small and large intestines
rectum
anus
The digestive system also includes the liver, pancreas, and gallbladder.
Your smooth muscles contract and relax as food passes through your body during digestion. These muscles also help push food out of your body through defecation, or vomiting when you’re sick
