Endocrine glands

The endocrine glands are also known as internal secretion glands. They are a series of glands that release substances such as hormones and have excretory duct with various functions in organs of the body , in turn extracted other substances from the blood and are secreted to subsequently be used for some part of the body. These glands secrete up to 20 hormones which are transported to organs and cells .


  • They are characterized by not having a link with the epithelium of which they were initially generated, which is why they do not have excretory ducts, said secretion is made directly into the bloodstream.
  • They are made up of groups of cells that are organized by clusters, follicles and cords.
  • These glands are regulated by the nervous system and in other cases by the same endocrine glands and in a third case it may be by a combination of both.
  • These glands can be found in the body within organs that fulfill endocrine functions, although at a parallel or secondary level, such as the kidney.
  • When a secretion higher or lower than normal occurs with respect to the hormones of these glands (hyposecretion and hypersecretion) it can lead to so-called endocrine diseases which especially affect development and growth, metabolism, sexual and reproductive functions. and even the mood of the people.
