What bones of the body also function as a storeage area for excess?

The bones of the body that also function as a storage area for excess are the long bones.

Long bones are those that are longer than they are wide, such as the femur (thigh bone), humerus (upper arm bone), and tibia (shin bone).

The interior of long bones is filled with a soft, spongy tissue called bone marrow. Bone marrow is responsible for producing the body's red blood cells, white blood cells, and platelets.

In addition to producing blood cells, bone marrow also stores various minerals, including calcium, phosphorus, and magnesium. These minerals help to strengthen bones and make them more resistant to damage.

Hence, long bones serve the dual purpose of providing structural support to the body and acting as a reservoir for important minerals and blood-forming cells.
