Study Notes
Overview of the Endocrine System
- A network of glands and organs that produce and regulate hormones in the body
- Hormones are chemical messengers that control various bodily functions
Major Endocrine Glands
-
Pituitary Gland: often referred to as the "master gland" because it regulates other endocrine glands
- Produces hormones that stimulate other endocrine glands
- Located at the base of the brain
-
Thyroid Gland: regulates metabolism and growth
- Produces thyroxine (T4) and triiodothyronine (T3)
- Located in the neck
-
Adrenal Glands: regulates stress response and electrolyte balance
- Produces adrenaline (epinephrine) and cortisol
- Located on top of the kidneys
-
Pancreas: regulates blood sugar levels
- Produces insulin and glucagon
- Located behind the stomach
-
Ovaries (in females): regulates female reproductive functions
- Produces estrogen and progesterone
- Located in the pelvis
-
Testes (in males): regulates male reproductive functions
- Produces testosterone
- Located in the scrotum
Hormones and Their Functions
- Insulin: regulates blood sugar levels by facilitating glucose uptake in cells
- Glucagon: raises blood sugar levels by stimulating glucose release from stored glycogen
- Adrenaline (Epinephrine): prepares the body for "fight or flight" response
- Cortisol: regulates stress response and metabolism
- Thyroxine (T4) and Triiodothyronine (T3): regulate metabolism and growth
- Estrogen: regulates female reproductive functions and development
- Progesterone: prepares the uterus for implantation of a fertilized egg
- Testosterone: regulates male reproductive functions and development
Functions of the Endocrine System
- Regulation of Metabolism: controls energy production and storage
- Regulation of Growth and Development: controls growth and development of tissues and organs
- Regulation of Electrolyte Balance: controls balance of essential minerals in the body
- Regulation of Reproductive Functions: controls reproductive functions and development
- Regulation of Stress Response: controls response to stress and danger
