Question

list any five potential specific functions of an integument in animals. Give examples where necessary

Answer 1

The integumentary system of mammals consists of the skin, hair, nails, glands, and nerves. The five potential functions of intigument in animals are as following...

• ​​​​​​Protection : Intigument protects body's internal living tissues and organs. It also works as a barrier against invasion by infectious organisms. The skin protects the rest of the body from the basic elements of nature such as wind, water, and UV sunlight.
• Sensory function : Intigumentary system in mammals has sensory function. It acts as a receptor for touch, pressure, pain, heat, and cold.
• Thermoregulation : The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system. It also protects the body from dehydration.
• Synthesis : In mammals, some parts of the intigumentary system help in synthesizing certain compounds which are important for the growth and development of the body. The epidermal layer of human skin synthesizes vitamin D when exposed to UV radiation
• Storage and disposal : The intigument of mammals helps in storing water and fat. It also helps in disposal of waste materials.
