One of my carers is currently training to be a nurse. 

She did lots of papers and essays on everything from the nervous system to the exchange of gasses. All these nursing training essays to be used only once! What a waste...

There are many medical essays here with the subjects on the menu on the left,. Maybe others can learn something from them?  Since she had much trouble finding all this medical stuff and writing about it, I thought it might be a good idea to post it all up here for others!  Here it is reproduced with her permission.
