musculo-skeletal system

We tested our flexibility short term by doing a sit and reach test then after went on the trampolining for abit and after did the sit and reach test again that increases our flexibility because the synovial fluid helps you to become more flexible.
muscles pull and they work in pairs for example your try sep and bi  sep also your deltoid muscle makes the arm go up and the arm go down.
every bone in your body got an oppisite for example your elbows and knees and your hip and shoulder. you get more flexible when you warm up because their warm, you do a warm up because your bones are stiff and you need loosen up.

long term effects

as our muscles grow and bones get stronger, it increases flexibility and more sunuviul fluid and you get more cartilidge and increase lung capacity and have more red blood cells.
the amount of exerise you do makes the body fitter so it needs to be able to keep up with its self and your heart gets stronger and pumps more blood in one beat and this is called stroke volume.
with bone density the out side of the bone is called the compact bone.
also the bones  get stronger to cope with stress and all the stess you put threw them, also it helps you maintain health.
