Bones have several functions. The first and most obvious function is to make up the skeletal framework that provides rigidity to the body. Bones also provide a protective armor for vital areas of the body, including the rib cage that protect the heart and lungs, and the skull that protects the brain. Finally, bone marrow, the pulpy tissue that occupies the cavities inside the bones, manufactures all the body's red blood cells.

How many types of bones are found in the humen skeleton?

There are five main types of bones in the human skeleton: long bones (e.g. femur), short bones (e.g. carpals), flat bones (e.g. skull bones), irregular bones (e.g. vertebrae), and sesamoid bones (e.g. patella). Each type serves specific functions in the body's structure and support.
