THE ROLE OF ENDOCRINE SYSTEM IN HUMAN BEINGS
THE ROLE OF ENDOCRINE SYSTEM IN HUMAN BEINGS.
Endocrine system consists of glands that secrete hormones.
The glands have no ducts and are known as endocrine glands.
Other glands are known as exocrine glands because they have ducts.
The pancreas has an outer exocrine portion and an inner endocrine portion.
Hormones are chemical substances, protein in nature which are secreted at one part of the body and have effects on other parts not necessarily near the point of secretion.
They are secreted directly into blood and transported by blood.
Each hormone either has a generalized co-coordinating effect on the body or brings about a specific response in a particular target organ.
