- COn either side of the trachea
- DNear the heart
Correct answer
C. On either side of the trachea
Step-by-step solution
The thyroid gland is composed of two lobes which are located on either side of the trachea (Figure 22.3). Both the lobes are interconnected with a thin flap of connective tissue called isthmus. The thyroid gland is composed of follicles and stromal tissues. Each thyroid follicle is composed of follicular cells, enclosing a cavity. These follicular cells synthesise two hormones, tetraiodothyronine or thyroxine (T4 ) and triiodothyronine (T3 ).
