The integumentary system works with all other bodily systems—such as the nervous, cardiovascular, and digestive systems—to accomplish all the jobs it performs in helping to maintain the stability of the internal body.
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
