What are the functions of human bones?

This is a big question, and I can only count how much?

Construct the space and protect the organs within it. For example, the skull constructs the cranial cavity and protects the brain from external pressure on the inside; The ribs of the thorax and abdomen construct the ribcage and the abdominal cavity, and the things contained in them are vital organs; The pelvis constitutes the pelvic cavity and contains all the internal reproductive and excretory systems and the total digestive system; Most of the bones themselves are hollow, forming a bone cavity that is a container for bone marrow. Without bones, the vital organs of the human body cannot be effectively protected.

Supporting role. The human body is mainly determined by the skeleton, and a person with thick bones will not reach the realm of "delicate and soft bones" if he is allowed to reduce his skin and bones. It is also the function of bones that people can stand upright.

Hunchback is the result of bending and deformation of bones. As for the movement of joints, it is the role of muscles and tendons, which drive the movement of bones.

The endocrine function is represented by the hematopoietic function of yellow bone marrow and red bone marrow.

A certain storage function. Bones can store part of the mineral elements for the human body to use in extreme environments, long-term calcium deficiency will lead to osteoporosis, which is caused by a large loss of calcium in the bones, the loss of calcium is not wasted, but sent for other purposes, such as balancing the balance of blood potassium, sodium and calcium.

a.Protects, supports, hematopoiesis.

b.Hematopoiesis, exercise, immunization, storage.

c.Hematopoietic sun, exercise, immunity, celery storage, protection.

d.Hematopoiesis, Immunity, Storage, Protection, Support.

e.Hematopoiesis, movement, storage, protection, support.

Correct answer: d

Bones come in different forms. It can be basically divided into four categories: long bones, short bones, flat bones and irregular bones, and the functions of bones are as follows:

1 Long bones are long tubes that are distributed in the limbs and act as leverage in movement. Long bones have one body and two ends. The body, also known as the backbone, is dense in bone, and the cavity in the backbone is called the bone marrow cavity, which contains bone marrow; In a certain part of the body, there is a trophoblast hole where blood vessels enter and exit.

The ends, also known as epiphysis, are more enlarged and have a smooth articular surface, covered by articular cartilage. There is a layer of cartilage between the backbone and the epiphysis of the long bones of children, called epiphyseal cartilage. The epiphyseal cartilage can continue to proliferate and ossify, so that the length of the bone increases.

In adulthood, the epiphyseal cartilage ossification, and there are line-like marks left in the original epiphyseal cartilage, called the epiphyseal line.

2 Short bones are generally cubic in shape, mostly connected in groups, and are located in parts that bear weight and have complex movements, such as the carpal bones and tarsal bones.

3 The flat bones are plate-shaped and distributed on the head, chest, etc. It often forms the wall of the bony cavity and has a protective effect on the organs in the cavity, such as the cranial bone protects the brain, and the sternum and ribs protect the heart and lungs.

4 Irregular bone Irregular morphology, such as vertebrae. Some irregular bones have air-containing cavities called air-containing bones, such as the maxilla and ethmoid bone located around the nasal cavity, which can resonate when pronounced and can reduce the weight of the bone. ** on the Internet.

The basic role of bones: long bones, short bones.

Hello: Each bone has its function: it mainly plays the role of protection, support and movement.

Such as skull support, protect the brain; Thoracic support protects the heart, lungs, spleen, liver, etc.; The bones of the limbs are dominated by movement.

What are the functions of human bones?

Protective function: bones can protect internal organs, such as the skull to protect the brain; The ribs protect the ribcage.

Supporting function: Bones form a skeleton and maintain body posture.

Hematopoietic function: The bone marrow produces blood cells through hematopoiesis in the marrow cavity of long bones and the cavernous space.

Storage function: Bones store important minerals such as calcium and phosphorus.

Motor function: Bones, skeletal muscles, tendons, ligaments, and joints work together to generate and transmit force to move the body.

Most bones can perform more or less all of the above functions, but some bones are responsible for only a few of them.

Bones have the functions of supporting the body, protecting internal organs, completing sports, and participating in metabolism in the human body.

The human body is a whole made up of different bones connected by joints, ligaments, etc. The spine, in particular, supports the human body like a "pillar". Without the spine, it would be impossible for humans to stand and walk.

While supporting the human body, bones also protect various organs in the body, such as the skull protects the brain; The ribs protect the heart and lungs; The pelvis protects the uterus, bladder, etc. Without the protection of the bones, the chance of internal organ damage can be greatly increased by external impacts.

Bones, under the combined action of muscles, tendons, ligaments, and other soft tissues, allow people to walk and move, thus greatly improving the ability of humans to survive.

The involvement of human bones in the metabolism of the body is often not well understood, but in fact, bones are closely related to the metabolic processes of the whole body. For example, the bone marrow in the bones is the hematopoietic tissue; Bone contains a large amount of calcium, phosphorus and other substances, and is a participant and regulator of inorganic salt metabolism in the body.
