What is the difference between endocrine and exocrine gland

An endocrine gland is one that produces messenger substances known as hormones and pours them into the blood capillaries, which carry them to the cells that require them to perform their functions. An exocrine gland is one that is distributed throughout the body and is part of various organs, its function is to produce enzymes and other non-hormonal substances.

endocrine gland

It is a set of cells responsible for producing hormones, they pour them without an excretory duct directly into the blood capillaries to the white cells that require them to perform their function. Target organs, which are regulated by hormones, can also receive hormones. The main glands that make up the endocrine system are:

  • Pineal gland.
  • Thyroid gland.
  • Kidney glands.
  • Gonads: testicles and ovaries.
  • Liver.
  • Hypophysis or pituitary (posterior lobe and anterior lobe) Hypothalamus.
  • Pancreas.
  • Kidneys.

exocrine gland

Exocrine glands are a group of glands distributed throughout the body and are part of various organs and systems. They are responsible for producing non-hormonal substances that perform specific functions. These glands secrete chemicals through ducts that carry these substances to a cavity, organ, or body surface.

Differences between endocrine and exocrine gland

  • The endocrine system is made up of glands that produce hormones in order to regulate processes such as reproduction, development, growth, mood, and metabolism.
  • Some endocrine glands are: pituitary gland, pancreas, thyroid, adrenal glands, parathyroid, ovaries and testicles.
  • The exocrine system contains glands that produce and secrete substances that protect or lubricate our bodies.
  • Some exocrine glands are: sweat glands, salivary glands, mucous glands, mammary glands, sebaceous glands and lacrimal glands.
  • Substances produced by exocrine glands travel through ducts and are deposited on epithelial surfaces.
  • The endocrine glands are released into the blood and thus reach the cells and organs that require them.
