Explain thyroid glands

Thyroid is butterfly-shaped endocrine gland, located in the anterior portion of the neck. It consists of two lobes on either side of the trachea and parathyroid glands are present on their posterior surfaces.


There are two thyroid hormones such as Thyroxine (Tetraiodothyronine)/ T4 and Triiodothyronine/T3.

The Thyroxine hormone is secreted in the bloodstream and travels to the kidneys and liver. In these organs the T4 gets converted into its active form triiodothyronine.

Triiodothyronine hormone affects physiological processes such as growth, development, and metabolism.
