Study Notes
Endocrine System Definition
- The endocrine system is a network of glands that produce and secrete hormones internally
- Glands produce and release hormones, which are chemicals that travel to organs, skin, tissues, and muscles in the body
Endocrine System Function
- The main function of the endocrine system is to regulate and monitor hormone levels in the blood
- Hormones regulate moods, growth, metabolism, development, and reproduction
- The pituitary gland senses hormone levels and relays information to other glands to produce or stop producing hormones
Parts of the Endocrine System
- The endocrine system consists of several glands, including:
- Hypothalamus: regulates and controls the endocrine system, combining information from the nervous system and other glands
- Pituitary gland: produces hormones that control other glands, such as the thyroid and adrenal glands, and testes and ovaries
- Thyroid gland: regulates metabolism by producing the thyroid hormone
- Parathyroid gland: maintains bone health by balancing calcium levels in the blood
- Thymus gland: produces white blood cells (T-lymphocytes) and is critical for the immune system
- Adrenal gland: produces adrenaline and is responsible for the body's fight or flight response
- Pancreas: produces insulin, regulating sugar levels in the blood and controlling energy levels
How the Endocrine System Works
- The endocrine system continuously monitors hormone levels in the blood, maintaining homeostasis and optimal bodily functioning
- Hormones travel through the blood to target organs or cells, where they initiate cellular changes corresponding to their function
- The endocrine system regulates processes such as cellular metabolism, sugar and nutrient homeostasis, blood pressure, heart rate, sleep, digestion, and sexual development
