Question 9
1. Leverage: skeletal system allows movement by co-ordinated action ofmuscles on bones, providing leverage
2. Attachment of muscles: parts of skeleton (usually flat bones) providesurface for muscles to attach
3. Protection: skeleton protects vital tissues/organs e.g. skull protects
brain4. Shape/Support: skeleton gives body shape. Provides framework forsoft tissues (muscles, etc.) & prevent it from collapsing in heap
5. Blood cells: bones not solid - inside long bones are BONE MARROWwhich produce & replace white (generally in shafts of long bones) &red blood cells (generally at ends of longs bones & some flat bones)
6. Mineral store: skeleton acts as MINERAL RESERVE (e.g. calcium) vitalfor bone growth & health. Minerals transported round body whenneeded for growth/repair (e.g. injury)
