What Is Meant By An Integumentary System?

An integumentary system is an organ system that includes skin, hair, nails, and exocrine glands. 

Skin: It is the outermost and the largest organ of the human body. It protects the body from chemicals, UV rays, and other physical damage.

Hair: It is an accessory organ of the skin and helps in insulating the body. It also prevents the harmful UV rays from striking the skin. 

Nails: These organs are made of sheets of hard keratinocytes and are present on the distal ends of fingers and toes. 

Exocrine Glands: The exocrine glands secrete substances by means of ducts on the epithelial surface. Sweat glands, mammary glands, salivary glands, sebaceous glands are some of the exocrine glands.
