Document Summary
Homeostasis requires a balance between health and disease (ex. between inflammation & coagulation) Homeostasis is complex because not one individual system but multiple systems must work together. For burn patients, the loss of the integumentary system can impact at a critical level many other systems. It is essential for optimal conditions any change should bring body back to optimal conditions. Any inability to maintain homeostasis may lead to death or disease. These physiological controls have limitations where extreme conditions can disable the feedback mechanisms. The skin is the largest organ in the body and it is much more than a passive organ. Epidermis: outer cells are dead and act as protection and forms water tight seal. Deeper layers divide to produce stratum corneum and contains pigment to protect against uv radiation. Dermis: tough, elastic connective tissue which contains specialized structures including nerve endings, blood vessels, sweat glands, oil glands, and hair follicles.
