Endocrine glands
  1. Endocrine glands have no ducts - so these are also called as ductless glands Eg.Pituitary etc.,
  2. These glands secrete chemical substances called HORMONES directly into blood.
  3. Blood carries hormones to all the organs in the body. In other words blood acts as a medium of transport for hormones.
  4. Hormones act on the cells of other organs and increase or decrease the metabolism of carbohydrates, proteins and lipids.
  5. They make the cells to synthesize new proteins or make cells of the body to grow.
  6. They may even act on other endocrine glands and control their function.
  7. A hormone may act on one or more target tissues.
  8. Hormones act at very specific sites in the body. Same hormones may have different effects on different tissues.
