Question

bone cells that liquefy bone matrix and release calcium into the blood

Answer 1

The bone cells that liquefy the bone matrix and release calcium into the blood are called **osteoclasts**. Osteoclasts are large multinucleated cells that originate from monocyte/macrophage lineage and are responsible for the process of bone resorption. They break down the bone tissue by secreting enzymes and acids that dissolve the mineral components of the bone matrix, thereby releasing calcium and other minerals into the bloodstream. This process is crucial for maintaining calcium homeostasis in the body.
