Detailed explanation-1: -Thyroid hormone (T3 and T4) affects every cell and all the organs in your body by: Regulating the rate at which your body uses calories (energy). This affects weight loss or weight gain and is called the metabolic rate. Slowing down or speeding up your heart rate.

Detailed explanation-2: -Thyroid hormone affects virtually every organ system in the body, including the heart, CNS, autonomic nervous system, bone, GI, and metabolism. In general, when the thyroid hormone binds to its intranuclear receptor, it activates the genes for increasing metabolic rate and thermogenesis.

Detailed explanation-3: -Answer and Explanation: The correct answer is c. Follicle cells remove thyroglobulin from the follicle cavity by exocytosis. Follicle cells store the thyroglobulin to bind with iodine molecules and form thyroid hormones, and then it removes this thyroglobulin bonded with iodine molecule by exocytosis.

Detailed explanation-4: -Thyroid hormones The hormones made by the thyroid consist 80% of thyroxine (T4) and 20% of triiodothyronine (T3) and calcitonin. T3 and T4 increase your basal metabolic rate. They make all the cells in the body work harder, which affects things like body temperature, heart rate, bowel function, and many more.
