1.2  Why we need a skeleton


                  1.2  Why we need a skeleton






              Focus

              1   Match the bones of the skeleton with their functions.

                  Draw lines from the names of the bones to their function.
                  Different bones can have the same function, or more than one function.

              Practice

              2   Read the text about skeletons and answer questions about what you

                  have read.

                     Our skeleton supports our body. It makes a strong frame inside

                     the body. It gives our body shape and makes it firm.

                     Our skeleton also protects organs inside the body.

                     We grow and get bigger because our skeleton grows.
                     We begin to grow at birth. Our bones get longer and thicker

                     each year.

                     When we are about 18 to 20 years old, our bones stop growing.

                     Sometimes we fall or have accidents and break our bones.

                     A broken bone is called a fracture. Doctors take special photos
                     called X-rays to see if a bone is broken or not. The broken ends

                     of the bone slowly grow back together again.
