Integumentary System

The integumentary system is composed of the skin, hair, nails, and exocrine glands. The skin is the largest organ in the body and serves as a barrier between the internal environment and the outside world.

The hair and nails are appendages of the skin that provide protection and insulation. The exocrine glands produce substances that keep the skin healthy and help to regulate body temperature.

The skin is composed of two layers: the epidermis and the dermis. The epidermis is the outermost layer of the skin and is made up of dead cells that provide a barrier against infection.

The dermis is the inner layer of the skin and is composed of living cells that provide strength and elasticity. The hair and nails are made up of keratin, a protein that is also found in the epidermis.

The exocrine glands are responsible for producing sweat, which helps to regulate body temperature, and sebum, which keeps the skin healthy.

Sweat is produced by the eccrine glands, which are located in the dermis. Sebum is produced by the sebaceous glands, which are located in the epidermis.
