This assignment will be completed in pairs. (only two people, no groups
of 3+)
You may select your partner for this activity.
The objective of this assignment is to solidfy your knowledge of the 11
body systems.
You are going to write a 1 page letter explaining why you are breaking up
with your significant other. Your significant other is your partner, who is
also a body system.
For instance, I am skeletal system, and I am breaking up with my
significant other, digestive system.
You will have to include at least 10 facts about your and your significant
other’s body systems.
Examples of good sentences:
 “Digestive system…I can’t be with you anymore..all you do is eat and stuff
your fat esophagus with proteins and fats…can’t you do anything besides
process food into nutrients? Maybe take me on a date every once and a
while!”
