1. in terrestrial vertebrates, what is the advantaged of having the surfacesfor oxygen and carbon dioxide exchange embedded deep in lung tissue?
2.the capillaries that lie in close contact with the alveoli are branches ofwhat blood vessel?
3.the confluence of these capillaries forms what blood vessel?
4.compare blood composition in adult circulation with reference to oxygenand carbon dioxide between capillaries approaching alveoli andcapillaries leaving alveoli. the capillaries approaching the alveoli contain low oxygen and highcarbon dioxide, and the capillaries leaving the alveoli contain high oxygenand low carbon dioxide.
