The Human Body System

​This is the Skeletal System

The skeletal system is composed of bones that composed of protein, collagen, and minerals, especially calcium. Collagen provides a framework for the incorporation of mineral, mainly calcium phosphate into the collagen framework. The mineral makes bone hard and strong while the collagen provides flexibility so that the bone can resist breaking.

This is Muscular System

The muscular system is a body system that allows for movement, posture, and circulation. It's made up of three types of muscle tissue: cardiac, smooth, and skeletal:

• Skeletal muscles: Attached to bones, these muscles enable voluntary movement. They make up the majority of the muscular system, with almost 650 in the human body.

• Cardiac muscles: These muscles make up the walls of the heart.

• Smooth muscles: These muscles control movement in internal organs and structures.
