Osteoclasts are specialized cells responsible for breaking down bone tissue. They play a crucial role in the process of bone remodeling, which involves the continuous renewal and reshaping of bones. By resorbing bone, osteoclasts help maintain calcium levels in the body and support overall bone health. These cells originate from monocytes, a type of white blood cell, and are found on the surface of bones. Osteoclasts work in coordination with osteoblasts, which are cells that build new bone. This balance between osteoclasts and osteoblasts is essential for maintaining strong and healthy bones throughout life.
