But even the stuff that my body does hold onto doesn't last forever. Nothing lasts forever. We're all gonna die. (offscreen: This week on dear Hank and John) (laughter)

And another layer of cuboidal epitheli--ehhh. Epithelial! (offscreen: oh, oh, here we go) (groans)

Not only that, but the whole deal is lined with epithel-- epithelial (offscreen: oh god)

Not only that, but the whole deal is lined with epithelial tissue that's-- ahhhh, epithelial.

Not only that, but the whole deal is lined with epithel-- (laughter)

Not only that, but the whole deal is lined with epithel-- (exhales) I can't do it! (laughter) Epithelial. 

Where they can travel pretty much anywhere in your body (holding in laughter) and be used to do things - like keep you alive. (offscreen: it was good. I think we can do it again) But I did "epithelial" so well! (offscreen: I didn't even notice) Once I did "epithelial," I was like "I have to get it this time!" 

The stretch that runs from your mouth to your stomach unleashes all the mechanical and chemical prowers-- (rambles off)

Now you probably know that your kidneys are filters, and you may imagine them as sieves that strain out the bad stuff, leaving it sitting there like a hairball at the bottom of a-- (rambles off) (coughs)

And officially become an-- (flaps tongue) 

As your bladder fills up, impulses triggered by stretch receptors head to the pons and-- (cuts off) Haaah!

So food doesn't get directed down your espophagus and not up in (cuts off) Oh! So food does! Does get. Doesn't-- (sarcastically) You wouldn't want food in your esophagus, that'd be crazy! 

And we've covered it extensively in crash-- (chokes on words) 

Not sure why that helps with fighting or flighting! (imitates vomiting) And if like-- Oh, man! God! I guess-- I think I'm done with you. I am no longer interested in this fight. 

And the nucleotides. That's kinda-- the end there wasn't super good. Nucleot-- (imitates a robot shutting down)

Because a-- (rambles off) 

Other higher brain centers that give you the (exaggerates enunciation) conscious feeling that you have to be. (gasps) One more!

Other higher brain centers that gi-- (offscreen: Two more.)

And if your body senses an imbalance in blood sugar (pause) levels. (laughter)

Those molecules can then be processed and be used in the process that makes ATP or they might go on to-- (stutters) (rambles off)

The mucosa, the "sub-mucosta" (cuts off) "mucsosta." Why does my tongue do things I don't tell it to do? I don't understand.
