SBI3C Pig Dissection Tutorial

Watch the videos below for a walkthrough of the pig dissection.  There are some structures we talked about in class that were not mentioned in this video.  Note those.  Remember you need to know the function of the structures in addition to what they are.  There is a little quiz at the end you can do to reinforce your knowledge.
