This site has links to fourteen tutorials covering the fundamentals of  human physiology and anatomy including the symptoms and treatment of some common conditions and diseases. Each tutorial is complete with detailed labelled diagrams to assist understanding; after each section there is a quiz which is designed to elicit an understanding of the subject and not just a recall of facts. There is feedback for both correct and incorrect answers which is designed to be part of the learning material. The sections on conditions and diseases are not intended to facilitate self-diagnosis and should not be used for such purposes.  

You will have the opportunity to comment and submit feedback and you will be told your score from the quiz together with a pass of fail assessment. About 2 hours should be allowed for study and completion of each section. You can of course re-take the quiz as often as you like.   All the content is available without  subscription and you will not be asked to register or enroll; the site is for academic use and free of any advertising.

The Sample page gives examples of the level of the presentations and the contents of each section are  listed on the Sections page, then the Links page gives access to these Sections. The Feedback page  can be used  to report any problems with these pages.    Good luck!
