a. increases intestinal absorption of phosphorus and calcium from foods promotes bone formation regulates blood calcium levels
b. increases excretion of calcium from the kidneys calcium from foods promotes bone formation regulates blood calcium levels
c. increases excretion of calcium from the kidneys

Answer 1

The correct answer is option b. increases excretion of calcium from the kidneys calcium from foods promotes bone formation regulates blood calcium levels.

Step-by-step explanation:

The functions of vitamin D include several critical roles in maintaining bone health and calcium homeostasis. One of the primary functions of vitamin D is to increase the intestinal absorption of calcium and phosphorus, which are vital for promoting bone formation and regulating blood calcium levels.

Another important function is to facilitate the reabsorption of calcium from the kidneys, which helps to maintain normal serum concentrations of calcium and phosphate. Contrary to its other functions, vitamin D does not work to increase the excretion of calcium from the kidneys; instead, it promotes reabsorption.
