Nachos are delicious. And versatile because today they're also going to help us learn a thing or two about your digestive system. Nachos can provide us with energy and raw materials, by first ingesting something nutritious, propelling it through the alimentary canal where it will be mechanically broken down, and chemically digested by enzymes until my cells can absorb their monomers and use them to make whatever they need. And eventually, there will be pooping.
