1.Intake of which nutrients directly impacts thyroid hormone production?

2.Which hormone acts on bone to release calcium into the blood?
a.Thyroxine (T4)
b.Thyrocalcitonin
c.Triiodothyronine (T3)
d.Parathormone
ANS: D
Parathormone, or parathyroid hormone, is produced and secreted by the parathyroid glands. Low calcium levels will stimulate release of parathormone, which increases the plasma level of calcium. Parathormone acts on the renal tubules to increase the excretion of phosphorus in
the urine and to stimulate the reabsorption of calcium. Parathormone also acts on bone, causing the release of calcium from the bone into the bloodstream.

3.Which gland secretes epinephrine and norepinephrine?
a.Thyroid
b.Pituitary
c.Pancreas
d.Adrenal medulla
ANS: D
The adrenal medulla secretes epinephrine and norepinephrine.

6.Which action describes a function of aldosterone?
a.Conserve water
b.Excrete sodium
c.Constrict blood vessels
d.Excrete phosphorus
ANS: A
Aldosterone is classified as a mineralocorticoid. It promotes conservation of water by acting on the kidneys to retain sodium in exchange for potassium, which is excreted in the urine.
