Which of these is not an effect of PTH?
rise in blood phosphate level (PTH increases bone resorption which would increases Phosphate, but PTH also increases urine excretion of phosphate which tends to minimize the overall increase)
reduction of calcium excretion
increased intestinal calcium absorption (this is an indirect effect though the increase levels of Vitamin D)
increased number of osteoclasts
increased calcitriol synthesis
Which of these are effects of PTH?
rise in blood phosphate level (PTH increases bone resorption which would increases Phosphate, but PTH also increases urine excretion of phosphate which tends to minimize the overall increase)
reduction of calcium excretion
increased intestinal calcium absorption (this is an indirect effect though the increase levels of Vitamin D)
increased number of osteoclasts
increased calcitriol synthesis

Inhibition of osteoblast
Decreases calcium levels Changed the d to s on decrease, so it reads better
Inhibits osteoclasts
