Digestive System, Part 1: Crash Course Anatomy & Physiology #33
Digestive System, Part 1: Crash Course Anatomy & Physiology #33
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.

does anyone notice strong sad (from the Homestar-runner videos by the brothers Chapman) on his desk
Did anyone notice the jelly beans and eye balls that made there way onto the nachos > o <
soooooo i’ve been eating nachos… EVERY DAY ….for the last 3 weeks…. the canteen at school sells really good ones really cheep.. now i’m scared for my body.
Now I know how astronauts are able to eat! I’ve been asking myself "How does it go down if there’s no gravity????"
Going great until you mentioned "beef" & "cheese". Living with a humane diet, those don’t exist in my world, nor the enlightened plant based eating kids. Why do they always have to feature animal derivative foods in kid’s media? To normalize those "foods" so kids develop apathy towards the sources of those foods, such as taking kids to a petting zoo, where they adore the animals, then taking them to McDonald’s afterwards . They don’t make the connection.
amazing !
Perfect.
