Integument is a general term that refers to a layer of tissue that covers, encases, or binds the organs of a body. Common integument is found in animals and is the outer layer of skin. It is an organ consisting of a protective outer layer of keratinized cells that cover the body in humans and other animals.

The role of the common integument is as a barrier between the environment and the body. It helps protect against water loss, infectious agents, and other physical damage. It is also involved in thermoregulation and is filled with nerve endings for sensory perception.

Common integument has many functions, including protection from the elements, waterproofing, thermal regulation, and protection from pathogens. It also helps maintain the body's chemical balance, acts as a sensory organ, and produces hormones.

There are three layers of common integument: the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and is made up of several layers of cells. The dermis lies beneath the epidermis and is made up of connective tissue, blood vessels, and glands. The hypodermis, the innermost layer, is mostly made up of fat tissue.

The common integument is constantly regenerating itself. In humans, the cells of the epidermis slough off and are replaced by new cells from the deeper layers. This keeps the epidermis thick and resilient. The dermis also regenerates, replenishing the collagen and elastin fibers that give the skin its strength and elasticity.

There are a variety of diseases and disorders that can affect the common integument. These include skin cancer, psoriasis, and eczema. Injuries to the skin can also occur, including burns, cuts, and scrapes. Treatment for these conditions usually involves topical medications and creams, as well as lifestyle changes.

The common integument is a complex and important part of the body. It helps to protect, maintain, and regulate the environment. Keeping this layer of skin healthy is essential to overall wellbeing.
