Task 1 – Functions of the Skeleton. SHAPE + SUPPORT – Without the rigid framework that the skeleton provides the body would be a mass of soft tissue. It gives the body it’s shape and also provides support, holding vital organs in place. For example the vertebral column gives the body height and the ribcage supports the lungs. MOVEMENT – The bones of the skeleton gives the muscles something to attach to. Muscles work by contracting (shortens) and as they shorten they pull on the bones creating movement. PROTECTION – Some parts of the body are delicate and can be easily damaged. The skeleton helps protect them by providing a shield around them. Examples of this are the ribcage and sternum, which protect the heart and lungs. BLOOD PRODUCTION – Some of the larger bones contain bone marrow. Red and White blood cells are formed in the marrow cavities. Examples of these bones are the humerus, ribs and the femur. MINERAL STORAGE – Bones store minerals such as Calcium and Phosphorus. Calcium is responsible for keeping our bones hard. Calcium is broken down and used by the body, so a constant supply is needed to keep the bones tough. !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]þÿÿÿýÿÿÿ`abcdefghijklmnopqrstuvwxyz{|}~€Root EntryÿÿÿÿÿÿÿÿÀFàw¶Jh3Í@ ObjectsÿÿÿÿÿÿÿÿÿÿÿÿG¨Jh3Íàw¶Jh3ÍQuill ÿÿÿÿ G¨Jh3Íàw¶Jh3ÍEscher G¨Jh3Íàw¶Jh3ÍVBAÿÿÿÿÿÿÿÿÿÿÿÿG¨Jh3ÍG¨Jh3ÍEnvelope ÿÿÿÿþÿÿÿInternalÿÿÿÿÿÿÿÿÿÿÿÿ Contentsÿÿÿÿÿÿÿÿÿÿÿÿ_ yCompObjÿÿÿÿ^SummaryInformation( ÿÿÿÿX®DocumentSummaryInformation8ÿÿÿÿÿÿÿÿÿÿÿÿ˜EscherStmÿÿÿÿ ÿÿÿÿ þÿÿÿþÿÿÿþÿÿÿ
