Science Behind Body Wars - Part 2
4:30 -- Captain Braddock?...he's Eric Stratton from Animal House
He asks the scientist located inside the body what the "weather is like"
She responds
"98.6 actually it's a little warmer by the infection site"
Right again Disney!
Have you ever gotten a bug bite or a rash, and noticed the area around it was a bit warm? That's the white blood cells rushing to the site, increased blood flow to the site, increases the temperature of the specific area where the bacteria or infection is, so the WBCs can act quicker.
5:40 - there's a kid with a Figment hat on in the safety video
9:21 -
"Entry is set at 200 microns" - this is how small your ship will shrink to.
For a comparison 200 microns (10-6) = 200,000 nanometers (10-9). And most parts of cells are measured in nanometers...so while you are small...the cells of the body are much smaller.
You see in the video, the WBC's attaching onto the splinter...all good so far!
10:21
"Hang on, I'm being pulled into a capillary"
That's a feasible phenomenon.
Capillaries are among the least pressure filled regions of the circulatory system...meaning if you were sucked into one, the pressure wouldn't crush you, theoretically.
I'm being pulled toward the heart
Also makes sense
She's probably in a metarteriole -- and got pulled into a venule, which travels to the heart.
I can't make out the dialogue but I think the on-board comms guy says something about
"Watch your pressure"
Yes! It gets more pressure filled as you travel towards the heart!
"I'm in the Left Ventricle"
Venules turn into veins so it's plausible she could have been pulled into a pulmonary vein, and now into the left ventricle.
The flapping part that your ship goes through is the mitral valve opening and closing.
You head through another valve - the aortic valve...and head towards the lungs as the narration says.
-------------------
11:30 in the video.
Once you rescue Dr. Lair in the lung, she climbs aboard, but you need an energy boost.
She says
"The brain, it runs on electrical impulses"
11:50
"Okay we're in the heart's left atrium"
Check the chart again...pulmonary veins from the lungs end up in the left atrium!
"Okay, we're in the cerebral artery, taking us to the brain."
That is also, true...but a bit more complicated than they make it seem. Once you're in the left atrium, you can't just turn around and bounce off the heart...lol...you need to ride it around to catch the subclavian artery which connects like a superhighway to other arteries and going towards the brain.
12:21
"We're going to have to pass through the Blood Brain Barrier"
It's feasible.
"Cerebral cortex, we're inside the brain!"
"This neuron better fire"
Neurons are the cells of the brain that create action potentials via electrical impulses. Action potentials drive many of the engines of the brain...and the action potential in this instance gives the MET crew the impulse to beam them out and back to the lab.
And then the ride is over!
Well...hopefully you enjoyed that trip through Body Wars...It's a fun attraction. I wish it was still around...because it was pretty accurate for the most part...and to have a ride that jargon based in a theme park - that's awesome.
He's got Planet Coaster haha
