Study Notes
Overview
The endocrine system is a network of glands and organs that produce and regulate hormones in the body.
Functions
- Regulates growth and development
- Controls metabolic processes
- Maintains electrolyte and water balance
- Regulates reproductive processes
- Responds to stress
Glands and Organs
- Pituitary gland: Controls other endocrine glands, regulates growth and development
- Thyroid gland: Regulates metabolism
- Adrenal glands: Regulates stress response, electrolyte balance, and blood pressure
- Pancreas: Regulates blood sugar levels
- Ovaries (female): Regulates reproductive processes
- Testes (male): Regulates reproductive processes
- Hypothalamus: Regulates body temperature, hunger, and thirst
- Pineal gland: Regulates sleep-wake cycles
Hormones
- Insulin: Lowers blood sugar levels
- Glucagon: Raises blood sugar levels
- Adrenaline (epinephrine): Responds to stress
- Thyroxine (T4): Regulates metabolism
- Triiodothyronine (T3): Regulates metabolism
- Estrogen: Regulates reproductive processes (female)
- Testosterone: Regulates reproductive processes (male)
Disorders and Diseases
- Diabetes: Insulin deficiency or resistance
- Hypothyroidism: Underactive thyroid gland
- Hyperthyroidism: Overactive thyroid gland
- Cushing's syndrome: Overproduction of cortisol
- Hypogonadism: Underactive ovaries or testes
Interactions with Other Systems
- Nervous system: Regulates endocrine system function
- Immune system: Interacts with endocrine system to respond to infections
- Circulatory system: Transports hormones throughout the body
Learn about the functions, glands, and hormones of the endocrine system, as well as its interactions with other systems and common disorders. Understand how the endocrine system regulates growth, development, and metabolism.
