Examples of exocrine glands

The exocrine glands are a set of glands that are distributed throughout the body , forming part of different organs and devices that produce different non- hormonal substances that perform a specific function, such as enzymes . The exocrine glands are also called glands of external secretion .


10 examples of exocrine glands

  1. The sweat gland is a gland that is located in the reticular dermis and hypodermis and consists of long and thin tubes, closed at the lower end, where they are grouped, forming a ball.  Because of the pores that open to the outside, they secrete sweat , excess liquid fat, with a salty taste, and a texture similar to urine.
  2. The sebaceous glands are located in the middle dermis and formed by lipid- filled cells that develop embryologically in the fourth month of gestation, as an epithelial budding of the hair follicle .
  3. The lacrimal glands function to produce the tears that are lodged in the lacrimal fossa, which is located in the upper external part of each orbit. There are several accessory glands located on the eyelid, known as Meibomian glands , whose secretion is also part of the lacrimal gland.
  4. The pancreas is an organ of the digestive system and the endocrine system of vertebrates. In humans it is located in the abdominal cavity , just behind the stomach .
    It is both an exocrine and an endocrine gland . As exocrine secret pancreatic juice to the duodenum through the pancreatic duct . This juice contains bicarbonate , which neutralizes the acids that enter the duodenum from the stomach; and digestive enzymes , which break down the carbohydrates , proteins and lipids of food.
  5. The liver is an important organ that is present in both humans and vertebrates . The human liver has an average weight of 1500 g , is located in the upper right part of the abdomen, below the diaphragm , secretes essential bilefor the digestion of fats and has many other functions, including synthesis of plasma proteins , storage of vitamins and glycogenand detoxifying function. It is responsible for eliminating blooddifferent substances that can be harmful to the body including alcohol , making them harmless.
  6. The prostate , prostates , literally means “the one in front”, “protector”, “guardian” ) is an organ gland of the male reproductive system in most of mammals ,  chestnut- shaped , located opposite the rectum , below and at the exit of the urinary bladder, although it may be stuck to this one. This organ functions as a secondary bladder that exerts pressure so that the semen is expelled by the urethra to the outside; It also has the ability to close the passage of the bladder to prevent it from releasing its contents during intercourse .
  7. The salivary glands in various biological species are exocrine glands in the upper digestive system that produce saliva that they pour into the oral cavity.The Saliva is a liquid aqueous consistency, containing proteins , glycoproteins , carbohydrates and electrolytes , epithelial cells sloughed and leukocytes . Its function, among others, is to start the digestion of foods by moistening them to help in the process of chewing and swallowing and contains enzymes that begin the process of digestion of carbohydrates (amylase) and fats (salivary lipase)
  8. The mammary glands are the organs that, in all mammals produce milk to feed their babies or children during the first few months or weeks of life. These exocrine glands are sweat glands modified.
  9. The bulbourethral glands also known in classical terminology as Cowper’s glands , are two exocrine glands of the human male reproductive system. The classic name is due to the English anatomist and surgeon William Cowper (c.1666-1709), who described them for the first time.
  10. The  Bartolini glands  or greater vestibular glands are two glands tiny secretory on each side of the opening of the vaginal . Often they are not visible. They secrete a small amount of fluid that helps lubricate the vaginal lips during sexual function. This liquid also contains pheromones , so its mission is still discussed. Their homologous in the male are the bulbourethral glands .
