An osteoclast is a type of bone cell responsible for breaking down bone tissue. These cells play a crucial role in the process of bone remodeling, which is essential for maintaining healthy bones. Osteoclasts help regulate calcium levels in the body by resorbing bone, releasing minerals into the bloodstream. Osteoclasts are derived from monocytes, a type of white blood cell. They work in coordination with other bone cells, such as osteoblasts, which are responsible for bone formation. This balance between osteoclasts and osteoblasts is vital for bone health and overall skeletal integrity.
