What Are The Functions of The Skeletal System?
Skeletal system is formed by an organized set of bones (or skeletal organs) which together with other systems such as the nervous, joint and muscular, form the locomotor system.
The basic functions of the skeletal system are:
Serve as support:
Since they provide the body with a rigid support frame for muscles and soft tissues.
Protect the bones:
forming several cavities that protect the internal organs from possible blows. In this way the skull is responsible for the protection of the brain, while the rib cage, consisting of the ribs and sternum protects the lungs and the heart. Produce movement: Through the muscles that are inserted into the bones through the tendons and that thanks to a synchronized contraction, they produce movement.
Bone tissue stores minerals, especially calcium and phosphorus, which are necessary for muscle contraction and many other functions. In this way, when these minerals are necessary, the bone releases them into the blood that reloads them to distribute them to other areas of the body.
Production of blood cells:
Inside cavities that are located in certain bones, a connective tissue called bone marrow is responsible for producing red blood cells or red blood cells through a process called hematopoiesis.
It is a store of reserve fats:
Thus, the yellow marrow consists mainly of adipocytes with a few scattered red blood cells and is an important reservoir of chemical energy.
Structurally, the skeleton is made up of about 200 bones that are formed by bone tissue, cartilage, bone marrow and the membrane that surrounds the bones called (periosteum).
Also, the bones are not totally solid but have small spaces between their components forming channels through which circulate blood vessels that are responsible for carrying out an exchange of nutrients.
Depending on the size of these spaces, the bone can be compact that constitutes a protective and spongy support that allows the blood vessels to penetrate directly to produce an exchange of nutrients.
