Question

What is perspiration, and how does it relate to your skin?

Answer 1

Hint: The skin the layer of soft, flexible outer tissue covering the body of a vertebrate animal. It is responsible with the function of protection, thermoregulation, and sensation. It receives a number of different glands, blood vessels, nerves etc.

Complete answer:
The process through which sweating occurs is known as perspiration. It can be described as the production of fluids or water secreted by the sweat glands present in the skin of mammals. The skin of mammals’ bear numbers of different glands such as the sweat glands or the sudoriferous glands.

The sweat glands are small tubular structures present in the skin that produce sweat. They produce and secrete sweat substances by way of a duct onto the epithelial surface. Sweat glands are of two types which are eccrine sweat glands and apocrine sweat glands. Eccrine sweat glands are distributed almost all over the human body and secrets water-based secretion which is a primary form of cooling. Apocrine sweat glands are mostly found in the armpits and perianal area in humans but are directly not related to cooling of the body.

In humans, sweating is an important means of thermoregulation. The process of cooling of the body or thermoregulation in humans is achieved by the secretion of water-rich secretions known as sweat by the eccrine sweat glands. The sweat is released onto the surface of the skin which then evaporates due to its water-based composition. During hot weather, or when the individual's muscles heat up due to exertion, more sweat is produced from the body and it helps in the thermoregulation of the body.

The thermosensitive neurons are located in the preoptic and anterior regions of the brain's hypothalamus control the process of sweating. Sweating decreases core temperature through evaporative cooling at the skin surface. As evaporation of sweat from the skin takes place, it releases the energy absorbed from the body and decreases the temperature of the skin and superficial vessels.

Note: The skin contains a number of glands and sweat glands are responsible for the production of sweat. The process of sweating is known as perspiration. In hot conditions, the body regularizes the temperature through the process of sweating. The evaporation of sweat from the skin surface provides for a cooling effect and helps to decrease the body temperature.
