The muscular system is responsible for the movement of the human body. There are about 700 muscles in the human body. There are three types of muscles:
1. Smooth Muscles contain hollow organs like the stomach. Smooth muscles move by them selves, there never straight, our arteries and veins are located in our smooth muscles, and lastly the control a part of our eyes. it hold our digestive system too.
2. Cardiac Muscles make up our heart walls and are thick and strong. The only place this heart is found is the heart. This type of muscles is striated and is the strongest muscle in our body. These muscles are important for our breathing.
3. Skeletal muscles these long thin fibers are used in our daily movement. These muscles are attached to our bones to help us move in do our daily movement. Skeletal muscles look alternating bands of light and dark fibers called striations. Theses muscles are moved when you want to move and are controlled by the central nervous system. the tire quickly because of the filament of lactic acid and there very strong.
Smooth muscles are straitened like cardiac and skeletal muscles.
Smooth muscles are hollow cardiac is thick and strong and skeletal thick.
Smooth and cardiac muscles are involuntary and skeletal is voluntary.
