The Integumentary System It's the barrier between ourselves and the world around us...

= =

= Characteristic Lif e : = The integumentary system involves responsiveness (when the skin gets too hot, sweat is secreted from the skin or when it gets too cold goose bumps appear). Also there is growth in the skin (when the body grows, the skin stretches). Respiration is a part of the skin and the stimulation of the skin alters the respiration rate. When the skin absorbs oils and other water based molecules into its system, the characteristic of absorption is involved. The skin also excretes oils, sweat, and other impurities through it.

How does homeostasis work with the skin?:

 * sustaining homeostasis:
 * regulate body temperature
 * retards water loss from deeper tissues
 * houses sensory receptors
 * synthesizes various biochemicals
 * excrete small quantities of water

Organs:
When it comes to the integumentary system, there is only one organ involved, and that is the skin. The skin covers the entire body except for the fingernails, hair, eyelashes. The skin has two distinct layers of the skin: epidermis and dermis. The third layer is a "basement membrane" that is not technically considered for a layer.

The skin must use a metabolism in order to regenerate it skin. Everyday the dead skin is rubbed off the body, and the cells must have metabolism to regenerate the lost dead skin.

 * Metabolism is also required to keep skin alive and functioning as a protective barrier and a major contributor to maintaining the body's homeostasis ~Mrs. Rohland **
