During adolescence our bones become longer and heavier. what is the role of the osteoclasts in counteracting this additional body weight

During adolescence our bones becomes longer and heavier. The osteoclast helps in resorption of old bones to maintain calcium homeostasis.

Further Explanation:

The bones are metabolically active organ which undergoes remodeling throughout their life by resorption of old bone called osteoclast. Bones remodeling serves to maintain bones structure to make a change in its mechanical needs. Osteoclast helps in maintain plasma calcium homeostasis by resorption process.

Bone is a dynamic tissue which undergoes continuous renewing during the course of life which is called bone remodeling. Bone remodeling is the active and dynamic process that is needed for the correct balance it mainly depends upon to cells osteoblasts and osteoclast.

This is a collaborative function of two cells, osteoblast which helps in deposition of new bones that helps in repairing microfracture and osteoclast helps in absorption of old bones that helps in maintaining plasma calcium level. This process used to replace 10% of the skeletal tissue per year.

Osteoclast is the medical term for absorption of bones or which digest the old bones. They are multinucleated cells formed by fusion of mononuclear precursor. When the bone is little used than osteoclast removes the matrix and rid of unnecessary or extra mass. It reabsorbs the component from the old bones and released it into blood in response to use and disuse.
