Functions

1. The integumentary system protects the body from harmful bacteria while letting in ointments and medications to help the immune system. The skin is the first line of defense against injuries.

2. This system regulates the body's temperature. Located in the dermis, are several sensory cells that indicate when it is hot, cold, when there is pressure and so forth. These cells send information to the brain which then expands or contracts the blood vessels accordingly. Also located in the dermis are the sweat glands which produce sweat naturally when your body heats up.

3. The integumentary system produces vitamin D. Vitamin D is a vitamin that is not in a lot of foods so the body must naturally produce it. The integumentary system creates vitamin D through exposure to sunlight. Vitamin D is needed to absorb calcium and to grow strong bones.

4. The integumentary system stores glucose, fat, water, and salt. This section of the system is vital for storing energy to be used later and in case of emergency.

5. The integumentary system protects our bodies from uv radiation. Melanin is the part of the skin, located in the epidermis,that gives it its color as well as protects the body from the dangerous uv rays.
