Hello,
I major in Health Communications and I found the digestive system diagram (5th grade) you posted. I found the definitions and functions table- it was gloriously helpful as I have an A&P lab practical this week.
Nonetheless, my reason for contacting you is to praise you for the sphincter/valve sewing project. Really, I love science and I love crafting! What a great metaphor, too.
Amazing. Well Done.
