Answer 1

Thyroid Gland

• Location − Two lobes of thyroid gland are located on either side of trachea.
• Isthmus − Thin flap of connective tissue interconnecting the thyroid glands
• Composition − Follicles + Stromal tissues

• Follicular cells synthesise two hormones:

  • Tetraiodothyronine or thyroxine (T ₄ )
  • Triiodothyronine (T ₃ )

• Importance:

  • Regulates BMR (Basal Metabolism Rate)
  • Supports the process of RBC synthesis
  • Maintains water-electrolyte balance
  • Secretes thyrocalcitonin which regulates blood calcium levels
