Answer the following question:
1. Explain in detail why the thyroid becomes enlarged during an iodine deficiency? -
ANSWER-When iodine is lacking in the diet, the thyroid enlarges in what is called a
goiter. When the level of Thyroxin is low in the blood, the anterior pituitary gland still
produces TSH. The thyroid responds by enlarging and developing a goiter.
Aldosterone is involved in the regulation of sodium and potassium in the body.
Explain how too much aldosterone could contribute to high blood pressure. -
ANSWER-Aldosterone's primary target organ is the kidney, where it promotes renal
absorption of sodium and renal excretion of potassium. Too much sodium causes
retention of fluid and increases blood pressure. Therefore, too much Aldosterone will
causes increased and potentially high blood pressure.
