What Are Sweat Glands?
Sweat glands are single tubular glands, which can be divided into two types: exocrine sweat glands and apocrine sweat glands. Exocrine glands are the sweat glands we usually refer to. They consist of a secretory part and a duct part. The secretory part is located in the deep layer of dermis and subcutaneous tissue. See both light and dark cells.

- Sweat glands are single tubular glands, which can be divided into two types: exocrine sweat glands and apocrine sweat glands. Exocrine glands are the sweat glands we usually refer to. They consist of a secretory part and a duct part. The secretory part is located in the deep layer of dermis and subcutaneous tissue. See both light and dark cells.
Overview of sweat glands
- The secretory part continues directly as a duct. The duct of the sweat gland is thinner, and it runs from the deep layer of the dermis. After entering the epidermis, the duct opens spirally and directly opens into the sweat holes on the skin surface. Sweat secretion is the main way for the body to dissipate heat and plays an important role in regulating body temperature. The apocrine sweat gland is a special gland in the skin that produces special secretions. The apocrine sweat glands are larger, branched tubular glands, located in the dermis and subcutaneous tissue.
Physiological anatomy and significance of sweat glands:
- Simple single-tube glands in the skin. Distributed throughout the body with the palm and crotch as the most. In the deep dermis or subcutaneous tissue, the tubules coil into clumps and are the secretion of sweat glands. The extension from the secretory part to the epidermis is called the duct. After the catheter enters the epidermis, there is no tube wall, and the spiral channel finally opens on the skin surface, which is called sweat hole. The sweat glands secrete sweat, in which the evaporation of water on the skin surface can radiate body heat. Sweating is an important way for mammals to regulate body temperature. The composition of sweat is similar to urine. Human skin has more than 2 million sweat glands, which can be regarded as a special form of kidney. In the excretion of waste and maintaining the balance of water and salt, its function and the function of the kidney can compensate each other. When the kidneys are dysfunctional, the sweat glands can compensate part of the kidney's excretory function. The urinary cream accumulated on the skin surface of uremia patients is urea excreted by sweat glands.
- The sweat glands distributed in the underarms, areolas, genitals, and around the anus are called larger sweat glands. Their secretions are thicker milky substances that contain lipids and water. Lipid substances can produce unsaturated fatty acids after decomposition by bacteria and a special odor, like the fox's odor, is commonly known as odor. The sweat glands only gradually have secretory function during puberty. Some people have a stronger sweat gland secretion function than normal people. The sweat produced under the armpit and other places produces a odor of odor, which is a (limited) odor sweat or odor patient. The disease is prevalent in young people, especially young women. Female patients have a more significant odor before and after menstruation and during pregnancy. Some patients have a family history, and whether the sweat glandular secretions in these patients have special components that are easily broken down by bacteria is yet to be studied. Body odor does not affect physical health. Patients do not need to be overly nervous. The treatment is based on the principles of cleanness, dryness, sterilization, and convergence. Those with severe underarm odor who have failed other treatments can be resected with surgery, which has a good effect.
