Sinopsis

The endocrine system is a complex network of glands and organs that produce, regulate, and secrete hormones—chemical messengers that influence nearly every physiological process in the body. These hormones control metabolism, growth and development, reproduction, mood, and overall homeostasis. Unlike the nervous system, which relies on rapid electrical signals, the endocrine system operates through the bloodstream, allowing hormones to exert long-lasting effects on target organs and tissues. 
The endocrine system consists of several major glands, each responsible for specific hormone production. The hypothalamus, often referred to as the control center, regulates hormonal signals and maintains communication between the nervous and endocrine systems. It directs the pituitary gland, known as the "master gland," to release hormones that influence other endocrine organs. The thyroid gland regulates metabolism through thyroid hormones, while the parathyroid glands control calcium levels in the blood. The adrenal glands produce cortisol and adrenaline, essential for stress response and energy regulation. The pancreas, an organ with both endocrine and exocrine functions, plays a crucial role in blood sugar regulation through insulin and glucagon secretion. The gonads—testes in males and ovaries in females—produce sex hormones that govern reproductive functions and secondary sexual characteristics. Additionally, the pineal gland regulates sleep-wake cycles through melatonin production.
