You made this very easy to understand Thank you! (:
Comment from : @LariosGiveNoFucks

That is the reason poop is brown If it is really dark like black that means you might have a bleeding problem in your digestive system

0:26 that red blood cell looks yummy
Comment from : @hoopsonwheels

Great video! I think another reason why RBCs are biconcave is to increase surface area relative to the volume of the cell allowing for more efficient exchange of CO2 and O2 :) FYI, I love science too!

Comment from : @Amblydoper

That's because hair (and nails) is dead tissue Blood flows to the hair follicle to feed nutrients to the hair shaft so it can grow That's why it hurts to pull your hair out, because the tissue is living :)
Comment from : @musicbrain5

The blood doesn't go to ALL tissue - hair is tissue and I don't bleed when I cut my hair
Comment from : @KiloOscarZulu

Do the stem cells in nthe bone marrow have a replication limit? If yes, wouldn't donating blood make your life shorter?

This is the most correct comment that has ever been left on one of my videos
Comment from : @AlexDainisPhD

She definitely did this for the donuts The science was merely a framework in order to justify buying donuts
Comment from : @Wellwellwellwell1

Red blood cells do not contain DNA White blood cells do
Comment from : @zooks527

Thanks! This one was fun to make :)
Comment from : @AlexDainisPhD

"To much science" No such thing!
Comment from : @AlexDainisPhD

Between you ViHart Vsauce and JeffersonLab I learn way to much science
Comment from : @jonhowardlife

Hah, that might have been a little too messy :)
Comment from : @AlexDainisPhD

I was looking forward to seeing the filled donut squish so it could go through the capillary tape roll

Comment from : @AlexDainisPhD

Those nucleus are all bite sci-ze!! Ha ha, get the lame pun?
Comment from : @ArchOfWinter

Biologically, platelets are small cell fragments that help with blood clotting I know that when they take platelets as a donation, they're often used in cancer patients It's a weird process - they take your blood from one arm, run it through a dialysis machine, pull out what they need and push the rest back in through your other arm The blood coming back is cold, which feels very strange running back into your arm!
Comment from : @AlexDainisPhD

I have indeed, but I'm thinking science teacher via the internet is a pretty good gig for now!
Comment from : @AlexDainisPhD

I've never given just plasma before, but I have given just platelets! But any kind of donation is amazing! And delicious, of course!
Comment from : @AlexDainisPhD

Exactly!
Comment from : @AlexDainisPhD

think about being a teacher : )
