Not only does the skin hold everything in, it also plays a crucial role in providing an airtight, watertight and flexible barrier between the outside world and the highly regulated systems within the body. It also helps with temperature regulation, immune defence, vitamin production, and sensation.

What is the function of cutaneous?

Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature).

What is the importance of knowing the two layers of the skin?

The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
