Structure of the body : Bones form the structure of the body and give specific shape to the body.
Preservation : The soft parts of the bony body protect the heart, lungs, brain, spinal cord, etc.
Movement : Skeletal muscles control body movement through contraction and extension.
Red blood cell production : Red blood cells are produced from the bone marrow.
Immunity : A stable reticuloendothelial system increases the body’s immune system.
Breathing and hearing : Some of the unstable parts are modified to help in breathing and hearing.
Mineral salt storage : Bone stores calcium, phosphorus, potassium etc. About 97% of the body’s calcium is stored in bones.
Accumulation of toxic elements : If there are toxic elements in the body like lead, arsenic, etc., the bones store them.
As a junction : Acts as a junction of muscles, ligaments and tendons.
Pressure and Ionic Balance : Maintains the internal pressure and ionic balance of the body.
Hormonal action : Osteocalcin hormone is produced by bone marrow. This hormone regulates blood sugar and fat levels.
Chemical energy storage : As we age, some red bone marrow turns into yellow bone marrow. Bile bone marrow contains adipose cells. Adipose cells store chemical energy.
