ANATOMY

Detailed explanation-1: -Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it’s needed by other parts of the body.

Detailed explanation-2: -The central cavity of long bones is filled with marrow. The red marrow is responsible for forming red and white blood cells. It stores and releases minerals and fat.

Detailed explanation-3: -Stores minerals: Bones hold your body’s supply of minerals like calcium and vitamin D.

Detailed explanation-4: -Calcium is the major component of the bone, where it is present at more than 99% as calcium-phosphate complexes, and provides the skeleton strength and structure, making the bone a metabolic reservoir to maintain the intra-and extra-cellular calcium pool.

Detailed explanation-5: -Mineral storage – the bones themselves are made of minerals and act as a mineral store for calcium and phosphorous, which can be given up if the body requires the minerals for other functions. Attachment of muscles – the bones of the skeleton provide surfaces for the attachment of muscles.
