What are the three functions of bones

Bones are an important part of the human body. It can be said that without bones, human functions cannot be fully exerted. Bones play a relatively important role in the human body, for example. Bones can support the human body, enable people to perform various movements normally, and protect human organs. In addition, bones also enable people to have motor functions. Next, I will introduce to you in detail the specific functions of bones.

1. Supporting role

Bones are hard organs that make up the skeleton of vertebrates. Their functions are to move, support and protect the body, produce red blood cells and white blood cells, and store minerals.

Different bones in the human body are connected into a whole through joints, muscles, ligaments and other tissues, providing 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 effect

The human skeleton is like a frame that protects the important organs of the human body and avoids them from being interfered with 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. Sports Function

Bones work together with muscles, tendons, ligaments and other tissues to complete human movement 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 are closely related to human metabolism. 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.
