• a. Growth hormone (GH): It promotes cell growth and division.
• b. Antidiuretic hormone (ADH) or vasopressin: Acts on the kidneys to re - absorb water.
• c. Parathyroid hormone (PTH): Increases blood calcium levels by acting on bones, kidneys, and intestines.
• d. Calcitonin: Lowers blood calcium levels, mainly by inhibiting bone resorption.
• e. Oxytocin: Stimulates uterine contractions, especially during childbirth.
• f. Adrenocorticotropic hormone (ACTH): Stimulates the adrenal cortex to secrete corticosteroids.
• g. Insulin: Facilitates the uptake of glucose by cells, thus lowering blood glucose.
• h. Glucagon: Promotes glycogenolysis and gluconeogenesis, increasing blood glucose.
