Need for Endocrine System: -

  • We have seen that the neural system provides point-to-point rapid coordination among organs. 
  • Neural coordination is fast but short-lived. 
  • As the nerve fibres do not innervate all cells of the body and the cellular functions need to be continuously regulated; a special kind of coordination and integration has to be provided. 
  • This function is carried out by hormones. 
  • The neural system and the endocrine system jointly coordinate and regulate physiological functions in the body.

Endocrine Glands:

  • Endocrine glands lack ducts and are hence, called ductless glands. 
  • Their secretions are called hormones.
  • The classical definition of the hormone is a chemical produced by endocrine glands and released into the blood and transported to a distantly located target organ.
  • Hormones are non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts.

 

-Endocrine glands lack ducts and are hence, called ductless glands. Their secretions are called hormones. Hence, the correct option is b. endocrine glands
