Bones

Kids have more bones than adults because when we grow bigger in age some of our bones fuse with bigger bones. A baby is born with around 270 bones and an adult has around 206 bones. Bones have different shapes these are long bone, short bone, irregular bone and flat bone. The largest bone in a human body is the femur or a thigh bon and the smallest bone in a human body is the Stapes although it is really small it helps a lot by hearing. Inside the bone there is a soft substance called mallow. In the mallow there is two blood cells red and white. Red blood cells help transport oxygen through the body and white blood cells help fight diseases. If you break your shine bone it will grow back in a few weeks with the help of a cast. Babies have very soft bones because their bones contain more water. The hardest bone in the human body is the heel bone. Bones are white because of some minerals. Birds have light bones to fly and land animals and humans have heavier bones to support their body.
