What are the ingredients of bones? What are the components of bone?

The composition of bones includes two main categories: organic and inorganic.

The main components of organic matter in bones are collagen fibers, osteomucin and chondroitin sulfate. The collagen fibers in it provide support and tension, and the role of bone mucin is to bind calcium to the bones.

The main components of inorganic substances in bones are calcium phosphate and calcium carbonate. Bones and teeth make up more than 99% of the body's total calcium, while the other 1% is stored in the blood. When the calcium in the blood is insufficient, the calcium in the bones will be released into the blood, and when the concentration of calcium in the blood is high, the calcium will be sent into the bones for storage.

The ratio of organic to inorganic matter in bones is different at different stages:

In childhood, there are more than 1 3 organic matter and less than 2 3 inorganic matter;

In adulthood, organic matter accounts for 1 3 and inorganic matter accounts for 2 3;

In old age, there are less than 1 3 organic matter and more than 2 3 inorganic matter, and the elderly are prone to fractures, which is because the bones of the elderly contain relatively few organic substances, and the bones are hard but very brittle.

The bone matrix consists mainly of organic components (about 35%) and inorganic components (about 65%).

1. Organic components: including collagen fibers and amorphous matrix, accounting for about 35% of the weight of the backbone, are formed by bone cell secretion. 95% of the organic composition is collagen fibers (bone glue fibers), which are mainly composed of type I collagen, with a small amount of type V collagen.

2. Inorganic components: mainly calcium salt, also known as bone salt (bonesalt), accounting for about 65% of the weight of the backbone. The main component is hydroxyapatite crystal, CA10(PO4)6(OH)2.

Under the electron microscope, the crystals are finely needle-shaped, about 10 20 nm long, and they are arranged tightly and regularly along the long axis of collagen fibers. Once bone salt is combined with organic components, the bone matrix is stiff to accommodate its supporting functions.

It's not bones, it's water, because water accounts for 70% of the human body, and more calcium is in teeth and bones.

Yes, the most important ingredient should be bones. This is also the most correct result and has been tested accordingly.

I think the most important ingredient in the human body is bones, and there is a scientific basis for this.

I think the most important ingredient in the human body is bones, so I think it's bones.

The basic structure of bone: periosteum, bone, bone marrow.

Located in the outermost layer of bone, it is made up of connective tissue.

Contains blood vessels and nerves, osteoblasts.

It plays an important role in the nutrition and sensation of bones.

Bone density and cancellous bones.

Bone compact: distributed on the surface layer of the backbone. High pressure resistance.

Cancellous bone: Distributed in the interior of the dense bone.

It is characterized by being dense on the outside and hollow on the inside.

Fills in the void of the bone marrow cavity and cancellous bone.

Red bone marrow: hematopoiesis.

Bone is an important organ of the human body.

Bones are alive.

The internal structure of the bone helps to fulfill its function.

The structure of bone includes: periosteum, bone, and bone marrow. The periosteum is made up of fibrous connective tissue and is rich in nerves and blood vessels, which play an important role in bone nutrition, regeneration, and sensation.

The periosteum can be divided into two layers, the outer layer is dense and has many collagen fiber bundles that penetrate into the bone and make it anchor to the bone surface.

There are osteoblasts and osteoclasts in the inner layer, which have the functions of producing new bone and destroying bone respectively, and the function is very active in juvenile and directly involved in bone production. In adulthood, it becomes quiescent, but once a bone is damaged, such as a fracture, the periosteum regains its function and participates in the repair and healing of the fractured end.

Bones come in different shapes and sizes, for example, the arm bone is a long bone, the carpal bone is a short bone, the sternum and skull are flat bones, and the vertebrae are irregular bones. Adult bone is mainly composed of two types of tissue: hard, dense bone and porous cancellous bone, also known as cavernous bone.

The thigh bone, or femur, in the long bones, is mainly made up of dense bone with fat called yellow bone marrow in the middle.

Bone tissue is made up of a mixture of living cells and minerals, mainly calcium and phosphorus, which give bones their solid physical properties.

The raised bony ends are mainly composed of cancellous bone, surrounded by a thin layer of dense bone. Cancellous bone contains red bone marrow that makes blood cells. The surface of most bones is covered with a dense fibrous membrane called periosteum.

Blood vessels and nerve fibers pass through small channels on the hard outer layer of bone and enter the loose interior.

Period Inorganic organic matter Characteristics of bone.

The chemical composition of bone is mainly composed of organic matter and inorganic matter. The organic matter is composed of bone collagen and mucopolysaccharide protein, and its physical properties make bone elastic and tough. Inorganic matter is an inorganic salt (the main component is alkaline calcium phosphate), and its physical properties give bone a strong hardness.

This physical property of bone, which is hard and elastic and tough, depends mainly on the chemical spinal composition of the bone.

The organic matter and inorganic matter contained in the bone in early childhood account for about 1 2, so the elasticity is good, the plasticity is large and it is not easy to fracture, but because of the small hardness, it is easy to bend and deform, the organic matter in the bone in adulthood gradually decreases, the inorganic matter gradually increases, about 2 3, such a ratio makes the bone have a strong hardness and a certain elasticity and toughness, the bone collagen fiber aging in the bone in old age, the inorganic matter is relatively more, accounting for about 3 4, at the same time, due to the decrease in hormone level, the absorption and deposition of calcium and phosphorus are affected, and the bone appears porous, The total amount of bone tissue is also reduced, and the rough and coarse is osteoporosis, so at this time, the bone fragility is larger, the toughness is poor, and the rock town is prone to fractures.

Bone tissue is made up of a mixture of living cells and minerals (mainly calcium and phosphorus), and the main component of bone is calcium hydroxyphosphate, which can be dissolved with strong acids such as HCl.

Bones are made up of inorganic and organic substances, of which calcium is the main component of bones. Can be dissolved with strong acids, such as HCl. White vinegar can also be dissolved, but it has to be soaked for a long time.

Calcium carbonate, the main component of bones, in addition to certain phosphates, gums, proteins, etc. If you want to dissolve the bones, you can use strong acids, such as hydrochloric acid.
