Thyroid and Parathyroid

Thyroids are located in front of the trachea and consist of four small glands called parathyroid glands, which produce a hormone regulating the amount of calcium in the blood. Thyroids often become swollen when you are sick. ENTs make many diagnoses regarding the thyroid gland such as hyperthyroidism and hypothyroidism.
