Thankful Day #27

Thankful Day #27: I am thankful for my nephrons. Each kidney has about a million of these amazing structures that do the work of filtering and chemically balancing our blood--our entire blood volume every 5 minutes. After eating movie popcorn nightly for a week, I'm thankful that my nephrons kept me from swelling up like a water balloon.
