Endocrine glands
  • These are ductless glands (no tube to carry to various parts).
  • Their secretions are  directly released into the blood which carries them to various parts of the body.
Exocrine glands
  • The exocrine glands have ducts.
  • The secretions from these glands are carried through the ducts.
  • The ducts may open outside the body to release the secretions (e.g.sweat, milk) or may be released on to another surface within the body (e.g. Digestive juices)
  • These are chemical messengers that regulate physiological processes in living organisms.
  • They act upon specific cells/tissues/organs which are called target cells/tissues/organs. 
  • There are many types of hormones that act on different aspects of bodily functions and processes like growth and development.
