How our Muscles Work

This is an explanation about how our muscles function and why they do what they do. We have a total of 640 muscles in our body. Each muscle belongs to one of the three kinds.  The Skeletal, Cardiac and smooth muscles. Each all have a special job in our bodies that you might not even know they do.


The skeletal muscles are also called voluntary muscles. They are voluntary because we decide when to move them and how to move them. They are attached to our bones by what we call tendons. Bones, tendons and muscles all give our body strength. The are all part of the skeletal system which is controlled by our nervous system.


The Cardiac muscle is also called the heart. The Cardiac muscle has the special job of contracting and relaxing to pump blood throughout the whole body. The heart muscle is also known as the myocardium.

The last type of muscle is the smooth muscles which also have another name called the involuntary muscles. That means they work without you even telling them to or even trying.  They are found inside the walls of the stomach, the intestine and the bladder. The very hollow organs. They sit in between the outer covering and the inner lining. These walls help the food be processed through the stomach... Another way the could work is for example if you vomit they work by pushing the food from the stomach back through the esophagus and out the mouth. Next time when you eat you now know what happens to your food!
