Audio-visual PowerPoint presentation of the skeletal system

This is merely a rewrite/edit of a previous presentation done, I just need a couple more things added as well as a script to read off to record a voice-over narration to further elaborate on my presentation. This should provide further context and details.

The presentation needs additional information on the role of the skeletal system in homeostasis, as well as slides on the role of the skeletal system In protection.

This is a 12 slide presentation, slides/pictures/graphs can be removed/edited to allow information for the role of protection.

Information needs to be specific to the skeletal system ie. levels of organization for the skeletal system, bone cells/tissue, etc. The example and movement of blood calcium are good but more information is needed on how muscles pull on bones to create the movement. A functions slide would also be good.
