Endocrine System Overview

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

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

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

The endocrine system is a network of glands and organs that produce and regulate hormones in the body.
Hormones are chemical messengers that control various bodily functions.

Pituitary Gland: regulates other endocrine glands, producing hormones that stimulate their functions.
Pituitary Gland: located at the base of the brain.
Thyroid Gland: regulates metabolism and growth, producing thyroxine (T4) and triiodothyronine (T3).
Thyroid Gland: located in the neck.
Adrenal Glands: regulates stress response and electrolyte balance, producing adrenaline (epinephrine) and cortisol.
Adrenal Glands: located on top of the kidneys.
Pancreas: regulates blood sugar levels, producing insulin and glucagon.
