Question

Which is the outer layer of the skin that makes the body waterproof, gives it color, and helps to maintain hydration levels?

Answer 1

The outer most layer of the skin is called epidermis.

Explanation:

It forms the protective barrier over the body's surface . It is responsible for keeping water in the body and preventing pathogens from entering.

Keratinocytes are the major cells constituting 95% of the epidermis, while Merkel cells, melanocytes and Langerhans cells are also present.

The epidermis contains no blood vessels and cells in the deepest layers are nourished by diffusion from blood capillaries extending to the upper layers of the dermis.
