Anyone can answer this question!!!!
Get a piece of paper out
Team that picked this question will pick again after.
Draw the entire Aorta. Label all the branches superiorly, anteriorly, and laterally. Label all the way down to the Iliacs.
First team to raise their hand and be correct gets the points!
