Graduation Card - Physiology Themed

This cheerful card should make any AZ glad.  I received a request to make a box card with a physiology theme.  After a little questioning - as I really wasn't sure how I would make a physiology-themed card - I learned the card would be a graduation card for a University of Arizona student.  I convinced the customer the student would be wowed with a box card with a U of A theme.  But I did want to please the customer, so googled physiology to get inspired.  All you could find were pics of brains and bodies....so look carefully and you will see some physiological embellishments.

Good luck in the Elite Eight, Wildcats!
