Roma,
Doppler ultrasound devices can be used to measure blood flow through your body.
They bounce high-frequency sound waves off of red blood cells that are circulating through your body

tinabobina, not everything you learn in school is “useful” in later life but it shapes your brain and understanding more than you think! 😉

I think a lot of people got the correct answer to this thanks to watching The Big Bang Theory on TV.

I always heard it was a motorcycle not an ambulance. Kinda threw me off a little. Next thing you know, they'll be saying its how they track storms or something crazy like that???
