True
False
External nares are two openings through which air enters the nasal cavity from the outside.
True

Which of the following is false regarding the respiratory membrane?
it is the only barrier between the blood and the inhaled gases within each alveolus
basement membranes of alveolar type I cells and their adjacent capillaries are fused
oxygen cannot diffuse through the membrane and so must be actively transported
