Chapter 44, Problem 7A
Mild vitamin D deficiency can lead to osteoporosis, or reduced bone mineral density. This is thought to be due to an association with increased levels of
a. calcitonin, which leads to an increase in serum Ca2+ and bone loss.
b. PTH, which leads to an increase in serum Ca2+ and bone loss.
c. ADH, which reduces blood pressure and leads to bone loss.
d. insulin, which leads to a decrease in blood glucose and bone loss.
