Answer:
The skin helps cool the body on hot days through sweating and dilating blood vessels.
Explanation:
The skin, despite its appearance, is an organ, not a tissue as many people think. It is formed by two main layers, the epidermis and the dermis, which in turn are formed by different tissues. The skin has several functions in the body, one of the most important being maintaining temperature.
When it is very hot, the skin cools the body through sweat or vasodilation.
Vasodilation is the process of dilating blood vessels through the relaxation of the smooth muscles of the vessels and is related to the maintenance and regulation of body temperature, when it happens occurs the decrease in blood pressure and heat loss to the outside, cooling the body.
Sweat is a fluid produced by the sweat glands that are located in the dermis. Sweat has the function of cooling the body so that it does not get too hot. Sweating our body gets rid of the excess heat produced by metabolism or muscle strain.
