19. The addition of potassium iodide as a nutritional supplement to common table salt would most directly affect the function of which of these glands?
a) thryoid
b) sweat glands
c) adrenal cortex

the answer is a, thryoid, im assuming because of triiodothyronine. would someone please explain how this would affect the function of the thyroid? thanks in advance 🙂

because triiodothyronine is secreted by the thyroid as a function of the gland and it requires iodine for synthesis.
