How do the bones grow?

Answer 1

Bones are made of a network of calcium laid down by cells. As kids grow, special cells at the end of bones add new calcium to the network of the bone. Children have layers of these cells in the shape of plates at the ends of their bones. These are called growth plates, and they close up when kids reach their full adult height. The growth plates are open when you are born and the more and more that you grow, the more closed they become and eventually close for good when you are fully grown, which is usually around the age of 16 for the average child.

Yes, that's true and also this is right too ---> The skeleton of a fetus growing inside its mother's body does not contain hard bones. Instead, most bones start out as flexible cartilage. When a baby is born. it still has a lot of cartilage. As the baby grows, most of the cartilage is replaced by a bone.

The ones of a child continue to grow. The long bones lengthen at their ends, in areas called growth plates. The growth plates are areas of cartilage that continue to make new cells. Bone cells called osteocytes move into the cartilage, hardening it and changing it into bone. Growth continues into adolescence and sometimes even into early adulthood. Most bones harden completely after they have stopped growing. Even after bones have stopped growing, they can still repair themselves if they break.
