The Major Human Endocrine Glands & Their Hormones, Explained (Animated)

Dr. Purr takes a closer look at the major human endocrine glands and the hormones they send through the blood: the hypothalamus and its releasing hormones, the front and back lobes of the pituitary (growth hormone, TSH, ACTH, FSH, LH, prolactin, ADH, oxytocin), the thyroid (T4, T3, iodine, calcitonin), the parathyroids and calcium, the adrenal cortex (cortisol, aldosterone) and medulla (adrenaline), the pancreatic islets (insulin and glucagon), the ovaries and testes, and the pineal gland (melatonin), plus how the glands work together in feedback chains. ⚠️ Educational only.
