at 5:30 doesn’t the volume increase when the thorax expands?? Then the pressure decreases and oxygen goes in the spiricles at a faster rate ??

Thanks sir this video has really helped me

So Grasshoppers had been inhaling air through their head and exhale it with their butt?

[@winniethepooh8766]

thats one way to put it

[@maecameron2835]

why is the volume of the thorax reduced when it expands? surely that means the volume increases

[@leahhjamessx9833]

i thought this it must be a mistake - the volume must increase for air to be drawn in as volume and pressure have an inverse relationship, and for air to be drawn in the pressure inside must decrease to be lower than atmospheric pressure - meaning volume increases.

[@araclovechan2848]

Sorry I would like to ask when the thorax expands, doesn't the volume increase? However when you said this, you commented how it "reduces the volume" 5:35

[@user78832]

Nope the pressure increases and volume does indeed decrease :)

[@shoddy_buddy3014]

Great explanation. Lot of thanks from India 🇮🇳

Hi Sir,I am a teacher.your teaching style highly inspired me.kindly tell me what software you are using for making this videos

[@blueflames3367]

Yeah at 5:35 the volume in the thorax increases, pulling air in.
