Whta is layers of skin?

Answer 1

The skin is made up of three layers:

1. Epidermis: The outermost layer of the skin, the epidermis acts as a barrier to protect the body from environmental factors such as bacteria, viruses, and pollutants. It is made up of several layers of cells, including keratinocytes, melanocytes, and Langerhans cells.

2. Dermis: The middle layer of the skin, the dermis contains blood vessels, nerves, and sweat glands. It provides strength and elasticity to the skin, as well as nourishment and support for the epidermis. The dermis also contains collagen and elastin fibers, which give the skin its flexibility and firmness.

3. Subcutis (hypodermis): The innermost layer of the skin, the subcutis is made up of fat and connective tissue. It acts as a cushion to protect the body's organs and provide insulation. The subcutis also contains blood vessels and nerves that supply nutrients and sensation to the skin.
