    Use a fake name, Josh. Such as butterfly, or sister2, or honeybeebob. The purpose we have it is to track students questions if they have a followup.

    A typical pair of human lungs contain about 700 million alveoli, producing 70m² of surface area.

    area of each alveoli=totalarea/totalnumber

    areaeach=70m^2/700million
    = 70*10^6 cm^2/700*10^6
    = .1 cm^2
