You have learned from the previous module that the skeletal system provides framework and support to the body. You have also learned that bones are classified as axial and appendicular.
Do you know what other organs comprise your body and how they function? What organ covers your body? How does it protect you? The integumentary system is composed of organs that form the external covering of the body and protects it from many threats from our environment. Without
it, our muscles and other internal organs will be exposed to outside environment.
The integumentary system is composed of organs that form the external covering of the body and protect it from many threats such as infection, desiccation, abrasion, chemical assault and radiation damage. In humans the integumentary system comprises the skin and its appendages acting to protect the body from various kinds of damage such as loss of water and damages from the outside. It is also made of specialized cells that secrete melanin to protect the body from the carcinogenic effects of UV rays and cells that have an immune function. Sweat glands that excrete wastes and regulate body temperature are also part of the integumentary system.
