body. It is comprised of several different layers as well as many
derivative structures . There are several different types of skin
conditions, however most can be prevented with basic skin care.
The integumentary system is also studied and cared for by
several health care professionals.

essential part of the body and it’s functions. Equally complex is
the study of this system. However, the study of the
Integumentary System is a crucial building block of a medical
education.
