Integumentary system diseases


The largest organ system of our body is the integumentary system. It is comprised of human skin, nails, and hair. It is an amazing system we have that has so many interesting purposes and functions. Of these functions is its ability to waterproof the body. It does this through the assistance of the outer layer of keratinized and dead cells on our skin. Another function is to protect our body from losing water. It also aids our inner organs, protecting them from infections and germs which may attack our system. In all, this system is seen as our first line of defense for the body. The integumentary system does a lot more than that though. Aside from protecting the organs, it can sense pain, regulate temperature, excretes toxins, and plays a major part in helping to synthesize vitamin D.

Alopecia Areata – Alopecia Areata is an autoimmune disorder which is not contagious. What occurs here is that the immune system starts to attack the hair follicles.

There are also different types of warts that can appear such as the flat wart, common wart, genital wart, plantar wart, and mosaic wart. These are contagious and are shown to spread through contact from one person to another. They are said to look like a cauliflower or a solid blister that appears on the skin.
Athletes Foot – Tinea pedis, also known as Athlete’s foot is a fungal infection found on the skin. It’s symptoms are flaky, itchy and scaly skin that can appear in various areas. It is a condition that is found to be transmitted by walking barefoot in moist areas such as showers, pools, and bath houses.
