Question

define epidermis ?????​

Answer 1

The epidermis is the outermost of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss.

___________________________

• The epidermis is the thin, outer layer of the skin that is visible to the eye and works to provide protection for the body.

• This part of the skin does not contain any blood vessels and is, therefore, dependent on the dermis, which is the layer of the skin located directly underneath the epidermis, to provide access to nutrients and dispose of waste.
