Therefore, to strengthen bones, it is necessary to drink milk and eat plenty of small fish.
In addition, bones contain something called "carbohydrate" and water. Bones, like other parts of the body, receive oxygen and nutrients from the blood and expel unneeded substances into the bloodstream.
As a baby, the body's skeletal structure is small and soft, but it gradually grows into large, strong bones as it gains calcium and phosphorus.
Bones are strong and light because many of them are hollow, like a chickweed. Inside the bone is a soft substance called bone marrow.
The bone marrow is like a factory that produces red blood cells and white blood cells, important components of blood. This important factory is protected by the bone marrow.
Bones weaken considerably after a week of lying in bed due to illness. On the other hand, if you often carry heavy loads or exercise, your bones will become sturdy and strong. Even hard bones undergo such changes.
