digestion and voluntary and involuntary muscles

By RP Isaac

Muscles:

There are about 600 muscles in your body. The muscles that are not under your conscious control are called involuntary muscles. Involuntary muscles are responsible for activities such as breathing and digesting food.

Muscles:

The muscles that are under your control are called voluntary muscles. Smiling and turning the pages in a book are actions of voluntary muscles.

Skeletal Muscles:

Skeletal muscles are attached to the bones of your skeleton. Because you have conscious control of skeletal muscles, they are classified as voluntary muscles.

Cardiac Muscles:

Cardiac muscles are involuntary muscles found only in the heart. Cardiac muscles do not get tired.

Smooth Muscles:

Smooth muscles are called involuntary muscles because they work automatically. They are inside many internal organs of the body, and control many types of movements inside your body, such as those involved in the process of digestion. Smooth muscles react more slowly and tire more slowly than skeletal muscles.
