Skeletal System
The Skeletal system is the organ system whose primary function is to support and protect the body and to allow the body to move. The average adult has 206 bones. Bones help support and protect parts of your body. Bones also help your body maintain homestasis by storing minerals and making blood cells. The major organs of the Skeletal system are the bones.
Muscular System
The Muscular system is the organ system whose primary function is movement and flexibility. The muscular system is made up of the muscles that let you move. There are three kinds of muscle in your body. Smooth muscle moves food through the digestive system. Cardiac muscle pumps blood throughout the body. Skeletal muscle enables bones to move. Muscle action can be voluntary or involuntary. Muscle action that is under your control is voluntary. Muscle action that is not under your control is involuntary. Smooth muscle and cardiac muscle are both involuntary muscles. The major organs of the Muscular system are the muscles.
Integumentary System
The Integumentary system is the organ system that forms a protective covering on the outside of the body. The integumentary system covers your body and helps you maintain homestasis. The major organs of the integumentary system are your hair, skin, and nails.
Cardiovascular System
The Cardiovascular system is a collection of organs that transport blood throughout the body. The cardiovascular system helps maintain homestasis by performing many functions. For example this system helps maintain your body by carrying nutreints to your cells and removingwastes from your cells. The major organs of the Cardiovascular system are the heart, blood, and blood vessels.

Endocrine System
The endocrine system is a collection of glabds and groups of cells that secrete hormones that regulate growth, development, and homestasis. The major organs of the endocrine system are the hormones, pituitary gland, and the master gland. A hormone is a chemical messenger made in one cell or tissue in another part of the body.
