Muscles play a key role in the body, The muscular system is made up of 600 muscles in the human body, divided into three types: smooth, skeletal, and cardiac muscles. Skeletal muscles are the only ones we control voluntarily, while the heart and smooth muscles move automatically.
Each type of muscle has a specific job. For example, skeletal muscles let you walk, smooth muscles help with digestion, and the heart muscle keeps your heart beating on its own. In this article, we'll look at 9 muscle functions.
Function one: Movement
Skeletal muscles control your movements and are partly managed by the nervous system, You use your skeletal muscles every time you move, Some twitches happen and help you make the best moves.
The second function: blood circulation
The heart muscle and smooth muscles help pump the blood so it flows through your body, and the nervous system controls it automatically, and it makes it pump blood by creating electrical pulses, the heart muscle has a central smooth muscle, and there are also many smooth muscles in the blood vessels that carry blood to all body organs.
The third function: breathing
The main muscle in Breathing is the diaphragm, Deep breathing like the kind you feel when exercising moves many muscles including the belly, neck, and back muscles.
Fourth function: digestion
The digestive system has a lot of smooth muscles, they are:
- Mouth
- Esophagus
- Stomach
- Small and large intestines
- Rectum
- Anus
These muscles tighten when food passes through. They help move food through your digestive system to finish digestion and keep going until you get rid of it, or throw up if you’re sick.
Fifth function: urination
The urinary system is divided into smooth muscles and skeletal muscles, which are:
- Kidneys
- Bladder
- Ureter
- The urethra
- The penis or vagina
- The prostate
All these muscles work together during urination. When these muscles tighten, you can hold urine, and when they relax, you can urinate.
The sixth function: childbirth
Some smooth muscles were found in the uterus, Those muscles stretch as the child grows, and when it's time for birth, those muscles contract and relax to help push the child out.
Seventh function: vision
The eye socket has 6 internal muscles, Their job is to move the eye, There are other internal muscles too, and those are smooth muscles that help complete the vision process. If these muscles get damaged, your sight can be affected and it might cause vision weakness.
Eighth function: stability
The skeletal muscles inside you help protect your spine, andlet you keep your body stable in a safe position for you, these are the core muscles like your back, belly, and pelvis, also called trunk muscles. The stronger these muscles are, the better your body stability is.
The ninth function: Your posture
