Mammalian Integument

The mammalian integument, commonly called skin, is a complex protective covering that shields the body from environmental hazards, helps regulate temperature, and prevents water loss. It consists of multiple layers, including the outer epidermis made of dead skin cells and the inner dermis that contains blood vessels, nerves, hair follicles, and glands. The skin also produces sweat and oils to maintain health and protect against infection. Overall, the integument is vital for survival, serving as a barrier, sensory interface, and temperature regulator, ensuring mammals stay healthy and adapt to their environment.
