NTR 401 Exam 2 Questions and Answers
100% Verified Graded A+
1. nephron
Answer: functional unit of the kidney
consists of glomerulus, Bowman's capsule, proximal and distal tubules, & loop of Henley
2. osteoclasts
Answer: cells in the bone that use HCl and proteases to dissolve bone mineral matrix
3. calcitriol
Answer: 1,25 dihydroxycholecalciferol
stimulates Calbindin (Ca binding protein) increases
blood Ca levels from gut and bone
active metabolite of vit D
, ditterent from calcidiol
4. calcidiol
Answer: excreted from liver when activated by vit D marker
for vit D status
vit D --> liver --> calcidiol --> kidney --> calcitriol --> small int --> increase serum Ca
closest way to measure change in serum Ca levels
regulated variable
5. phylloquinone
Answer: the chemical from of vit K that is synthesized in plants
6. promotes the uptake of minerals
Answer: lactose
oxalic acid, tannins, and phytate REDUCE mineral uptake
7. the pituitary hormone chiefly responsible for regulating the amount of
water that is excreted by the kidney in response to change in the osmotic
pressure of the blood: ADH
