The topic of section sixteen is the pathophysiological changes that can occur in the integumentary system. These include inflammatory reaction of the skin and the formation of lesions, burns, cellulitis, dermatitis, folliculitis, furuncles, carbuncles, fungal infections, pressure ulcers, psoriasis, scleroderma, toxic epidermal necrolysis and warts. All these possible alterations mentioned applies to physiology because the integumentary system, which consists of the skin, the subcutaneous tissue below the skin, hair, nails and assorted glands protect our body from invading microbes (chemically and physically), regulates body temperature, prevents dehydration, acts as a blood reservoir, aids in excretion and vitamin D synthesis. The skin is the largest and heaviest body system, and it takes a lot of work to keep it balanced. It is considered one of the most valuable parts of the body. Since the skin is our first line of defense, we must take necessary precautions to keep it healthy and prevent any kind of infection from developing and spreading. The hair and nails both have protective functions in addition to their cosmetic appeal. The integumentary system has two main types of glands, sebaceous (oil) and sudoriferous (sweat). The sweat glands function primarily in thermoregulation by the production of sweat, and sebaceous glands produce oil that keeps the skin and hair from becoming dry and serves as a bactericide.

It was extremely informative to read all about the causes of the disorders, the signs and symptoms, complications, diagnosis, treatments and special considerations.
