The Body Systems

The Integumentary system is the skin system. The skin includes protection, temperature regulation, sensory reception, biochemical synthesis, and absorption. The skin provides a protective barrier for the Immunity system, defending exposure from harmful bacteria and infection. The skin also compliments the urinary system. The skin acts as a waste disposal. Certain waste is expelled from the body 24 hours a day through the skin in the form of excess water, toxins and carbon dioxide. Sweating is an example of expelling toxins. The skin has a lot to do with the nervous system. The skin provides people with a sense of touch to help them communicate with the outside world. It responds to sudden changes in emotions. For example, when getting scared, the hairs on the back of the neck will stand up. Also when sexually aroused, the skin becomes more sensitive. The skin is the body's main organ of sexual attraction.

The musculature system is the muscle system. The musculature system is the biological system of an organism that allows it to move. Otherwise, its main job is to provide movement for the body. The muscular system in vertebrates is controlled through the nervous system. The nervous system moves the muscles through reflexes and by sending messages from the brain to the muscles. The muscles make it so the skeletal system can move. The muscles connect bones together and allow them to function properly. The Integumentary system (the skin) layers the muscle. The skin can stretch as the muscles grow, adapting to the change. The skin can act as armor too, giving the muscles a little extra protection against cuts and hard hits, thus for causing bruising.

The circulatory system is the body system that that moves nutrients, gases, and wastes to and from cells, and helps maintain body temperature. The circulatory system consist of the heart, the blood, and the blood vessels. The circulatory system interacts with the respiratory system through pulmonary
