Part 2 will provide an overview of the accessory structures of the skin and their functions. Maintaining a constant core body temperature (37°C) is an important function of the skin and this regulation is essential for the normal functioning of cellular enzymes throughout the body. Being homoiothermous animals, with temperatures around 35 C (rabbit 36 C), their metabolism is regulated to work best at a particular temperature and therefore is must be constantly regulated.
