骨质的化学成分由有机成分和无机成分组成。有机成势呈要是胶原蛋白，无机成

The chemical composition of bone consists of organic and inorganic components. The organic form is collagen, and the inorganic components are mainly calcium phosphate and calcium carbonate. The organic matter makes the bone have certain elasticity and toughness, so the wood is easily broken under the action of general external force. Inorganic matter has a certain hardness, so that the bone can withstand certain pressure and muscle tension. If the bone is burned and the organic matter is removed, only the inorganic matter remains in the bone, which becomes very brittle and easily broken. If the bone is soaked in hydrochloric acid, the inorganic matter is removed, and only the organic matter is left, then its hardness disappears, and its elasticity and toughness are fully revealed. At this time, it can be curled into a bone knot.

The chemical composition of bone consists of organic and inorganic components. The organic potential is collagen, and the inorganic components are mainly calcium phosphate and calcium carbonate. Organic matter makes bone have certain elasticity and toughness, so wood is easy to break under the action of general external force. Inorganic materials have a certain hardness, so that bone can withstand a certain pressure and muscle tension. If you burn the bone and remove the organic matter, the bone will only have inorganic matter. At this time, it becomes very brittle and easy to break. If the bone is soaked in hydrochloric acid, the inorganic matter is removed and only the organic matter is left, its hardness disappears and its elasticity and toughness are fully exposed. At this time, it can be curled into a bone knot.
