Question

which hormone inhibits osteoclasts and stimulates osteoblasts to lower blood calcium levels? multiple choice calcitonin calcitriol parathyroid hormone insulin aldosterone

Calcitonin is a hormone that inhibits osteoclasts (cells that break down bone) and stimulates osteoblasts (cells that build bone), thus lowering blood calcium levels. Calcitriol increases blood - calcium levels. Parathyroid hormone also increases blood calcium levels. Insulin is related to blood - glucose regulation. Aldosterone is involved in salt and water balance.

A. Calcitonin
