The Integumentary System

Jordan Kincaid, Period 5

The Components (Organs and Tissues)

Three things that make up the integumentary system are skin, hair, and nails. There are two layers of the system; the dermis and the epidermis. The epidermis acts as a jacket, covering the inner layers while the dermis contains nerves and blood vessels. This system also contains sweat glands, which help to keep our temperature level. Sweat glands often get rid of too much water, leading to dehydration if you aren't cautious. Athletes often drink lots of water to prevent this.

The Integumentary System and its Functions

The integumentary system is very important in that it has a number of useful functions.

1) It helps to protect inner organs. The epidermis covers the whole body, making it significantly more difficult to access it.

2) It protects the body from dehydration. The sweat glands often sweat excessively during workouts or just from sunlight so you have to drink lots of water.

3) It helps protect the body from abrupt temperature changes by either sweating or shivering. Sweating helps to decrease temperature, and shivering forces some of your hairs to shiver, increasing warmth.

4) It protects the dermis from sunburns. Melanin in our skin helps to protect our dermis.

5) It helps to store water, fat, and vitamin D.

Diseases in the Integumentary System

The integumentary system may be safe, but a number of diseases can occur here. One of the most common skin diseases is skin cancer, diagnosing more than two million people in the U.S. every year with this. Warts are another disease happening on our skin, rough bumps caused by a viral infection. One of the most well known skin diseases is acne- a disorder of the hair and oil glands.

Skin Cancer

Cancer has a number of treatment options, an oncologist being the doctor you would go to. Certain types of cancer, if not treated carefully, can be fatal. For more of the common types of cancer, chemotherapy is advised and often used.


Warts are rough bumps caused by viral infection. Though any physician can treat them, often a dermatologist is called. Most often to get rid of them people freeze them, use liquid irritation, and sometimes use lasers.


Often acne is dealt with by using home remedies or face wipes. It's one of the most common skin diseases yet not one of the worst. Acne is often found on your face, back, and chest.
