What We Did Today:
- Pop quiz on respiratory system. I think. Unless that was the day before, which is also possible.
- Learned more stuff about the respiratory system - partial pressures, reviewed the mechanics of breathing, etc.
- Finished watching Osmosis Jones.
Thoughts / Opinions:
- I hate these bullet points.
- How do these cilia in your trachea work, do they just hang out and stick around or do they wiggle or what do they doooo?
Above and Beyond!:
- According to http://www.lung.ca/children/grades4_6/respiratory/how_we_breathe.html, "Millions of tiny hairs called CILIA act like tiny brooms to sweep out the bad stuff caught in the mucus. Each cilium sweeps back and forth about ten times every second! That's 36,000 every hour, 24 hours a day! They do this to keep your lungs clean."
- I also just noticed that this is grades 4-6, so I guess I'm behind on these things and should have known?
- Oh, I also found out that you have like six hundred million alveoli in your lungs. That's six hundred million grape-like sacs. That's almost disgusting.
