Exocrine Glands

An exocrine gland is an exocrine gland. These channels secrete material to the surface of the body. There are skin infections, breast infections, sweat infections and some non-gastrointestinal infections.

Structure Of The Exocrine Glands

The structure of the exocrine glands is divided into two parts:

  1. Ductal portion
  2. Glandular portion

The tubular section is tubular. It is a single, thick, cube-shaped cell wall that helps transport secretions. The tube can be branched or unbranched. It can also be viewed as a simple coil structure.

The gallbladder is responsible for the production of secretion. It is a group of cells that are round or oblong. The cells found in this gland depend on the secretion of fluid. For example; Serous cells secrete proteins, mucous cells secrete fluid.

Functions Of Exocrine Glands

They perform the following functions:

  • Regulate body temperature
  • Lubrication
  • Lactation
  • Helps in digestion
  • Helps in reproduction

Types of Exocrine Glands

  • Holocrine Glands
  • Merocrine or Eccrine Glands
  • Apocrine Glands

These are released by breaking the plasma membrane. These, produced in the cell cytoplasm, destroy the cell and release the product into the lumen.

Excretion occurs directly into the duct via the cellular pathway. There was no breakdown of the cell wall involved.

They germinate part of their cytoplasm and membrane and secrete the material in a tubular form.

Examples of Exocrine Glands

  • Lacrimal Glands – There are tear ducts near each eye.
  • Pancreas – In addition to digestive enzymes, pancreatic juice is secreted in the pancreas.
  • Salivary gland: Secretes saliva along with digestive enzymes.
  • The liver secretes saliva containing salts and digestive substances.
  • Mastitis: secretion of milk from the breasts.
  • Eccrine Sweat Glands – secrete salt water through sweat.
