| A | B |
| pituitary gland | Master Gland- releases GH, TSH, ACTH, ADH, Oxytocin |
| Thyroid gland | Makes Thyroxine and other hormones important in metabolic regulation |
| Parathyroid gland | Makes bones release Ca+ back to blood in response to low calcium levels |
| Adrenal | Epinephrine production |
| Pancreas | Insulin and Glucagon production |
| Thymus | Makes hormone thymosin which stimulates the production of T cells (for immune system) |
| Pineal Body | releases melatonin |
| Ovaries | produce Estrogen and Progesterone |
| Testes | produce Testosterone and other male hormones |
| Oxytocin | stimulates contraction of uterus- positive feedback loop in childbirth |
| ADH | acts on kidneys to concentrate urine and conserve fluid |
| Prolactin | develops breast tissue and stimulates milk production |
| Growth Hormone | normal growth of body tissue |
| thyroid stimulating hormone (TSH) | stimulates growth of thyroid tissue |
| Melanocyte-stimulating hormone (MSH) | increases skin pigmentation |
| Follicle stimulating hormone (FSH) | stimulates maturity of follicles to produce estrogen |
| Insulin function | to lower blood sugar by activating glucose uptake from blood by body cells |
| Glucagon function | to raise blood sugar by triggering liver to breakdown glycogen |
| Calcitonin | produced by thyroid gland - triggers skeletal system to take in calcium to lower blood calcium |
| Hypothalamus | Gland that connects nervous system and endocrine system: Master control gland |
