The upper respiratory tract differs from the lower respiratory tract in what way?
A) air is taken in through the lower respiratory tract, and CO2/O2 are exchanged in the
upper respiratory tract
b) air is taken in through the upper respiratory tract, and CO2/O2 are exchanged in the
lower respiratory tract
c) CO2 is removed from circulation in the upper respiratory tract
d) O2 is removed from circulation in the lower respiratory tract - correct answer. B. Air
is taken in through the upper respiratory tract, and CO2/O2 are exchanged in the lower
respiratory tract

There is no net air flow into or out of the lungs when
a) P alveolus = P atmostpher
b) P alveolus< P atmostphere
c) P pleural wall > P atmostphere
d) P atmosphere< P pleural wall - correct answer. a) P alveolus = P atmosphere

What keeps the lungs from collapsing

Check the - correct answer. b) trans pulmonary negative pressure caused by negative
pressure from pleural cavity

Identify the correct sequence of events for inspiration
a) diaphragm & inspiratory intercostals relax, lungs expand, air flows into alveoli
b) diaphragm & inspiratory intercostals contract; lungs expand, air flows out of the
alveoli
c) diaphragm & inspiratory intercostals contract, lungs expand, air flows into alveoli
