Question
Chapter 5, Problem 5RQ
Summary Introduction
To determine:
The factor that accounts for the waterproof nature of the skin.
Introduction:
The integumentary system is constituted by the skin as well as its appendages. The skin functions to protect the body from various agents such as chemicals, invading microorganisms, and ultraviolet (UV) radiation. It is also engaged in body temperature regulation, excretion, vitamin D synthesis, as well as sensory reception.
