Living systems require coordination and integration. Endocrine and nervous systems are the control systems of the body. Endocrine control can be divided in to :
  • Slower
  • Longer acting

This two systems are interrelated  and act to maintain homeostasis. Endocrine glands make hormones and this hormones released into blood, circulate throughout the body, act only at “receptor sites” on target cells.
Hormones control several major processes. These are
  • Reproduction
  • Growth and development
  • Mobilization of body defenses
  • Maintenance of much of homeostasis
  • Regulation of metabolism
