Y1 E4 Gas exchange in the lungs

Back after the half-term holiday, with a discussion on gas exchange specifically in the lungs. I'd love to get your feedback if you're listening as I want these episodes to be genuinely useful in your A level bio journey. Leave a review, leave your feedback so I can improve things, too. Many thanks!

Y1 E3: gas exchange in insects

you're still here? umm ok....then let's talk how insects carry out gas exchange bearing in mind the three key features of any gas gas exchange system. sweet.
