CVS Lab Visit

The list includes all the structures you will see in lab and for which you may be tested on the lab practical. Note that any vasculature included on this list may also be tested (via MCQ) on the block exam. 

Most structures are linked to SketchFab XR resources demonstrating the structure and its relational anatomy. You may find it helpful to preview these structures prior to lab or review these structures after lab. You may scroll through the labels to learn more about the relevant anatomy.
