What is the role of the skin in metabolic processes and heat regulation?

Heat regulation in the human body is produced by the central nervous system. The skin has an important function in this process. The hypodermis and epidermis are weak conductors of electricity and heat. The skin is involved in the process of regulating heat and due to the presence of a significant number of blood vessels in it. The blood vessels of the skin increase when the ambient temperature rises, which leads to an improved heat transfer from the skin. With a decrease in ambient temperature, a reflex decrease in blood vessels occurs and heat transfer becomes worse.
