What are the uses for the ribs in terrestrial vertebrates for taking air into the lungs?
intercostal muscles between the ribs make the rib cage expand, that will create an underpressure in the longs so air will flow in :D
o-O You got a source for that, sir? cx
well yea Campbell Biology ninth edition :P
I can try to find it on the internet if you'd like that
If only I knew how to cite a book. Cx

And how to cite a book: \(\sf Name(year)\it book ~\sf City, State: Publisher\) So for my book that would be: Reece, J. B., Urry, L., Cain, M., Wasserman, S., Minorsky, P., & Jackson, R. (2011). Campbell biology (9th edition; International edition.). Harlow: Pearson Education
o-O
Or you can also only say the name of the first author followed by et al (which means and others) Reece, J. B., et al. (2011). Campbell biology (9th edition; International edition.). Harlow: Pearson Education
