BIOD 151 Module 6 Exam
1. List the hormone(s) that best describes the statement below: I lower the level of
calcium in the blood by depositing calcium into bone. - ---------------ANS: Calcitonin
2. List the hormone(s) that best describes the statement below: I promote the
reabsorption of water at the collecting ducts of the kidneys. - ---------------ANS: ADH
3. List the hormone(s) that best describes the statement below: I am secreted by the
pituitary and stimulate the gonads. - ---------------ANS: FSH, LH, (Gonadotropic
hormones)
4. List the hormone(s) that best describes the statement below: I am secreted by the
pituitary to stimulate the thyroid. - ---------------ANS: TSH
5. List the hormone(s) that best describes the statement below: I am secreted by the
beta cells of the pancreas. - ---------------ANS: Insulin
6. List the hormone(s) that best describes the statement below: I am secreted by the
pituitary to stimulate the adrenal cortex. - ---------------ANS: ACTH
7. List the hormone(s) that best describes the statement below: I am secreted by the
alpha cells of the pancreas. - ---------------ANS: Glucagon
8. List the hormone(s) that best describes the statement below: I cause blood
glucose to rise and breakdown stored nutrients. - ---------------ANS: Glucagon
9. Answer the following question. Explain in detail how PTH and calcitonin work to
maintain calcium balance. - ---------------ANS: Calcitonin: produced by the thyroid
glands, deposits calcium into bone. Calcitonin opposes the ac!on of PTH. When the
blood calcium level reaches the appropriate level through all these means, the
parathyroid glands stop producing PTH through nega!ve feedback. PTH: produced
by the parathyroid glands increase the amount of calcium in the blood. (Any one of
the following explana!ons of PTH is acceptable) PTH s!mulates the increased
absorp!on of calcium from the intes!nes. PTH retains calcium through excre!ng
phosphate at the kidneys. In the bones, PTH promotes the ac!vity of osteoclasts to
demineralize of the bone, increasing the amount of calcium in the blood.
10. Explain why it would be harmful to have an increased secretion of ACTH in
someone who is diabetic. - ---------------ANS: ACTH controls the secretion of cortisol
from the adrenal cortex. Increased levels of ACTH would cause increased levels of
cortisol within the blood. Cortisol increases blood glucose levels which will decrease
the effectiveness of insulin treatments.
