The Importance of Bones in the Human Body
would not have the shape which is seen by others. It would have no power to sit, stand or move. Essential minerals such as calcium and phosphorus are stored and distributed by them. Blood cells are produced by the red marrow which is contained in the spongy centers of bones.
The human skeleton, consisting of 206 bones, is a marvel of engineering. The bones which form the skeleton consist of proteins and mineral substances. Whenever the bones meet in the human body there is a joint formed which performs a special function in our body. Some big joints such as hip and shoulder joint perform many functions at the same time. Some other joints, such as those in the skull, are totally immovable. Movable joints are supported by ligaments. Muscles also move and support the joints to some extent.
Without bones, the human body would not have the shape which is seen by others. It would have no power to sit, stand or move. Essential minerals such as calcium and phosphorus are stored and distributed by them. Blood cells are produced by the red marrow which is contained in the spongy centres of bones.
The bones in males are larger and heavier than the bones in the female. The female pelvic cavity is wider than the male pelvic cavity. If it were not so it would be difficult for a woman to give birth to a baby in the normal manner.
The human legs carry a lot of weight for a lifetime. The fingers of the hand can catch hold of an object and manipulate it in a delicate fashion, and with these artists create immortal paintings and sculptures. The rib cage is a protective cushion for the heart, the lungs and major blood vessels of the body. The pelvic girdle protects and supports the internal organs of the lower abdomen. The spinal cord or the backbone is protected by the surrounding vertebral column.
The skeletal system also plays an important role in the protection of the vital organs throughout the body. This protective role is perhaps most obvious for the skull and the backbone (vertebrae) as these bones protect the central nervous system. This protective role is especially important because the central nervous system controls the rest of our body and is very fragile. The ribs also protect the vital organs in the chest, such as the lungs and heart.
The skeleton gives the body its shape, which changes with growth. In addition to determining characteristics such as height and the size of the hands and feet, stable body shape enables essential functions.
This is how we understand bones are so much important to our body.
