Answer 1

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

☞︎︎︎Exchange of gases is across pressure/ concentration gradient. Exchange of gases occurs between alveoli and blood and between blood and tissues.

☞︎︎︎The difference in the partial pressure of CO2 (pCO2) and O2 (pO2) in alveolar tissues, blood and other body tissues, results in diffusion of gases across membranes.
