Biology, tongues and hair!
Biology, tongues and hair!
Hi and welcome to your 60 Second Coffee Break!
I'm Chris Dabbs and this is episode 38!
Pay attention, this episode is all about biology...
Did you know that if they were laid end-to-end all of the blood vessels in the human body would circle the Earth four times!
And, did you also know, your tongue is made up of eight muscles, similar in structure to an elephant's trunk or an octopus' tentacle.
Now, hair grows about six inches per year, the only thing in the body that grows that fast is bone marrow.
And, if you ever wondered what causes you to blush, it's actually a rush of adrenaline.
And finally...why couldn't the bike stand up for itself...it was 'two tyred' (or 'two tired' if you're American) :)
Here are some great episodes to start with.
