What are the functions of bones?

When I was in school, I knew that the human body has a total of 206 bones. What are the functions of bones and how many points are they divided into? Usually, I only know that the human body, like animals, is supported by bones. Without bones, the human body is like cotton. When children were young, every mother hoped that her children could grow taller, and growing taller means bone growth. Today, I am here to introduce to my friends the functions of bones and how many points are they divided into.

(1) Supportive role: Different bones in the human body are connected into a whole through joints, muscles, ligaments and other tissues, which provide support for the body. If humans did not have bones, they would just be a pile of soft tissue lying on the ground, unable to stand, let alone walk. (2) Protective function: The human skeleton is like a frame that protects the important organs of the human body and avoids them from being disturbed and damaged by external forces as much as possible. For example, the skull protects the brain tissue, the spine and ribs protect the heart and lungs, and the pelvic bones protect the bladder and uterus. Without the protection of bones, external impacts and blows can easily damage internal organs. (3) Motor function: Bones work together with muscles, tendons, ligaments and other tissues to complete human motor functions. Bones provide the necessary support for movement, muscles and tendons provide the power for movement, and the function of ligaments is to maintain the stability of bones so that movement can continue. So, we say that bones are the basis of movement. (4) Metabolic function: Bones have a close metabolic relationship with the human body. Bones contain large amounts of calcium, phosphorus and other organic and inorganic substances, and are participants and regulators of inorganic salt metabolism in the body. Bones also participate in the regulation of human endocrine system, affecting the secretion and metabolism of hormones in the body. Bones are also related to the balance of electrolytes in the body. (5) Hematopoietic function: The hematopoietic function of bones is mainly manifested in human childhood. The bone marrow cavity contains a large number of hematopoietic cells, which are involved in the formation of blood. When people reach adulthood, red bone marrow with hematopoietic function still exists in some cancellous bones.

The above content is an introduction to the functions of bones and is divided into several points. Do you have a new understanding of bones now? Treat your bones like you would treat your friends. If you treat them well, they will treat you well. We should protect our bones from getting injured since childhood. When we are old, our joints will not hurt and our bones will be as flexible as when we were young.
