Q

Pathophysiology of Bone Process

A

-bones are constantly undergoing process of renewal
-osteoclasts break down the old cells, releasing CA in blood stream
-osteoblasts build new ones, removing CA from the bloodstream
W/ Osteoporosis:
-this process gets out of balance and more bone cells are lost than are replaced
-leads to porous bones that are less dense and easy to fracture

27
Calcium Mechanism of Action
Calciu, is essential to bone development. Calcium is also critical to the nervous, muscular, and cardiovascular systems.
