Sweat produced by sweat glands
Also known as sweat glands, they are epithelial cells present in the skin of mammals, including humans.
Function of the sweat glands
These glands have the important function of secreting sweat, allowing the regulation of body temperature and the elimination of toxic substances to the body.
Types Of Human Sweat Glands
More in the human body than the apocrine glands, eccrines are present in almost every part of the skin. They act mainly in the process of regulating body temperature through evaporation. This happens because with the evaporation of sweat the body loses thermal energy.
They are most commonly found on the skin of the palms, soles and forehead. They start working soon after the birth of the child.
The part that excretes sweat from the eccrine glands is found mainly in the deep dermis. The sweat excretory duct passes through the dermis, epidermis and ends in the pores of the skin surface.
The sweat that is produced by this type of gland has in its composition mainly water, urea, ions, amino acids, ammonia, lactic acid and glucose.
They are present mainly in the armpits, areolas of the breasts and areas of the face where beard is born (in men).
The duct that conducts sweat from this type of gland is present in the subcutaneous mesh, ending in the hair follicles.
The sweat produced by these glands is composed of water, ions, ammonia, amino acids, proteins, lipids, urea, lactic acid and glucose. However, this sweat has a somewhat sticky consistency.
These glands begin to produce sweat only at the puberty stage. They come into play mainly in sexual relations and in times of stress.
- A professional soccer player can lose 2-3 liters of sweat during a 90-minute match. Therefore, hydration before and during games is of fundamental importance.
