Difference between Gland and hormone

A gland is a set of cells that synthesize chemicals such as hormones while hormones are substances secreted by endocrine glands or by epithelial cells in order to influence the functioning of other cells.

Gland

The glands are a group of cells whose function is to synthesize chemical substances, such as hormones, in order to release them into the bloodstream, on the surface of the skin, or inside a body cavity.

The glands can be classified into:

Endocrine: It is known as closed glands, they lack a duct and discharge their secretion into the capillaries that surround them.

Mixed: They produce substances that are excreted both outsides and into the bloodstream.

Exocrine: It is known as open glands and they secrete their products through an excreta tube that secretes their product towards the surface or towards the lumen of a hollow organ. They are classified into three groups:

  • Apocrine.
  • Holocrine.
  • Merocrines.

Hormone

Hormones are substances that are secreted by specialized cells located in endocrine glands or by epithelial or interstitial cells in order to influence the functioning of other cells.

Hormones belong to the group of chemical messengers. All multicellular organisms produce hormones. The hormones most studied in animals and humans are those produced by endocrine glands, but hormones are produced in almost all organs.

There are natural hormones and synthetic hormones, the latter is used to treat certain disorders.

Difference between gland and hormone in points

  • Glands are groups of cells whose purpose is to synthesize and excrete chemicals to release them into the bloodstream, in an organ, or on the surface of the skin.
  • Hormones are substances that are secreted by specialized cells and whose purpose is to function in other cells.
