Explanation:

Calcitonin is a hormone that inhibits osteoclasts, increases bone deposition, and causes kidneys to excrete calcium. It also has its level increased in pregnant women. However, it does not cause less calcitriol to be secreted. Calcitriol is the active form of vitamin D and its secretion is regulated by other factors mainly related to parathyroid - hormone and calcium levels.
