Biology: The Endocrine System

The endocrine system is a network of glands and organs that produce and regulate hormones in the body.
Hormones are chemical messengers that help control various bodily functions, such as growth and development, metabolism, and reproductive processes.

Pituitary gland: often referred to as the "master gland" because it regulates other endocrine glands.
Thyroid gland: produces thyroxine (T4) and triiodothyronine (T3), which regulate metabolism.
Adrenal glands: produce hormones such as adrenaline (epinephrine) and cortisol, which regulate stress response and metabolism.
Pancreas: produces insulin and glucagon, which regulate blood sugar levels.
Ovaries (female): produce estrogen and progesterone, which regulate reproductive processes.
Testes (male): produce testosterone, which regulates reproductive processes.

Insulin: lowers blood sugar levels by facilitating glucose uptake in cells.
Glucagon: raises blood sugar levels by stimulating glucose release from stored glycogen.
Adrenaline (epinephrine): stimulates "fight or flight" response, increasing heart rate and blood pressure.
Cortisol: regulates stress response, metabolism, and immune function.
Thyroid hormones (T4 and T3): regulate metabolism, growth, and development.
Estrogen and progesterone: regulate reproductive processes, including menstruation and pregnancy.
Testosterone: regulates reproductive processes, including sperm production and libido.

Metabolism: regulation of metabolic processes, such as energy production and storage.
Growth and development: regulation of growth and development, including puberty and bone growth.
Reproductive processes: regulation of reproductive processes, including menstruation, pregnancy, and fertility.
Stress response: regulation of the body's response to stress, including the "fight or flight" response.

Diabetes mellitus: a condition characterized by high blood sugar levels due to insulin deficiency or resistance.
Hypothyroidism: a condition characterized by low thyroid hormone levels, leading to slowed metabolism and growth.
Hyperthyroidism: a condition characterized by high thyroid hormone levels, leading to rapid metabolism and weight loss.
Cushing's syndrome: a condition characterized by high cortisol levels, leading to weight gain, hypertension, and mood changes.
Hypogonadism: a condition characterized by low sex hormone levels, leading to reproductive dysfunction and infertility.
