Thyroid and Parathyroid

Thyroid: Secretes T3 and T4 (regulates BMR, RBC formation, carbohydrate/protein/fat metabolism) and TCT (Thyrocalcitonin, lowers blood Ca2+); Parathyroid: Secretes PTH (Parathyroid Hormone), a hypercalcemic hormone that increases blood Ca2+ levels via bone demineralization and renal reabsorption.
