1. Digestion: Hormones like gastrin, secretin, cholecystokinin, pancreaginin, villikinin, enterogastrin etc. digest food.
2. Regulation of metabolism: Thyroxine, insulin, glucagon, glucocorticoid etc. hormones regulate sugar metabolism. The hormones testosterone and estrogen regulate protein metabolism.
3. Water balance: Antidiuretic hormone regulates water balance in the body.
4. Maintaining ion balance: Aldosterone hormone maintains the balance of Na+ and K+ ions in the body.
5. Puberty: During puberty, hormones such as testosterone, progesterone, estrogen, andosterone develop sexual characteristics.
6. Protein synthesis: Thyroxine hormone takes part in protein synthesis.
7. Red blood cell production: Erythropoietin hormone is released from the kidneys. It regulates red blood cell production.
8. Immunity: Thymosin hormone makes the body immune to diseases by producing lymphocytes and antibodies.
9. Reproductive Process: Testosterone and estrogen hormones stimulate the production of gonads and sexual intercourse. The hormone progesterone regulates pregnancy.
10. Blood pressure: Hormones like epinephrine, nor-epinephrine, vasopressin etc. increase blood pressure in the body.

Nervous red milky color blood pressure secretion labor
12. Milk secretion: Estrogen, prolactin, growth hormone etc. control the growth and milk secretion of the mammary glands.

14. Control of body color: Adrenocorticotropic hormone regulates body color by controlling the production of melanin.
15. Control of emergency situations: Adrenaline and no-adrenaline hormones cause vasoconstriction to release sweat and protect against emergency situations.
16. Excretion: Aldosterone increases the rate of K excretion and epinephrine decreases urine production.
