The thyroid is one of the largest endocrine organs, weighing approximately 15–20 gm in adults. The normal thyroid comprises two lobes joined by the isthmus Each lobe is approximately 2.0 or 2.5 cm in both thickness and width at its largest diameter and is approximately 4.0 cm in length. The gland has one of the highest rates of blood flow per gram of tissue of any organ in the body (5 ml/g/min), well in excess of the blood flow to the kidney (3 ml/g/min) [12].
