Study Notes
Endocrine System
- The endocrine system is a network of glands that produce hormones, chemical messengers that travel through the body, regulating various bodily functions.
- Exocrine glands secrete substances outside the body (e.g., sweat, saliva, digestive enzymes). Endocrine glands secrete hormones directly into the bloodstream.
- Hormones function throughout the body, affecting cells and organs.
- Hormones regulate metabolism, growth, development, reproduction, and much more.
- Hormones travel in the blood to target cells and bind to specific receptors.
- Products of endocrine glands are hormones that travel through the blood and influence target cells
Glands and their Hormones
-
Pineal gland (epiphysis): secretes melatonin, associated with regulating sleep-wake cycles.
-
Pituitary gland (hypophysis):
-
Secretes growth hormone, affecting growth and development.
-
Secretes other hormones that control other glands (e.g., thyroid, adrenal), thus regulating various functions like metabolism and reproduction.
-
Thyroid gland: produces thyroxine, influencing metabolism, growth, and development.
-
Parathyroid glands: regulate calcium levels in the blood.
-
Adrenal glands: produce adrenaline, affecting the body's response to stress, and regulate metabolism.
-
Pancreas: produces insulin and glucagon, important in regulating blood sugar levels.
-
Ovaries (female): produce estrogen and progesterone, influencing reproduction and development.
-
Testes (male): produce testosterone, influencing reproduction and development.
-
Other glands include the thymus, the parathyroid glands and the various endocrine cells found in the digestive system and other organs
-
Some glands, such as the pancreas, have both endocrine and exocrine functions.
