What are bones?
Bones are rigid tissues that make up the skeleton of the body.
Bones play many roles in the functioning of the body. Some of these are supporting and moving the body, protecting internal organs, producing red and white blood cells, and storing minerals such as calcium.
The human adult has 206 bones, while a human baby is born with 270 (which fuse over time).
The largest bone in the human body is the femur (the thigh bone), and the smallest are the ossicles which are found in the middle ear and enable hearing.
