Skin is actually the body's largest organ! Skin includes all four types of tissue - epithelial tissue, connective tissue, nervous tissue and muscle tissue.

Skin Function

Functions of the skin include protection, body temperature regulation, excretion of wastes, production of vitamin D and reception of sensory information from the environment. Skin layers and skin structures have different adaptations to carry out skin functions. The main layers of the skin include the epidermis, dermis and hypodermis. Within the main layers are sublayers with specialized properties.

Epidermis

The epidermis is the top layer of the skin containing stratified squamous epithelial cells. Epidermal squamous cells are keratinized, which means that they contain the tough protective protein keratin. The epidermis contains cells that produce keratin as well as cells that produce pigmentation, pick up sensory information and remove potentially harmful substances.
