- With Picmonic, get your life back by studying less and remembering more. Medical and Nursing students say that Picmonic is the most comprehensive and effective way to bridge learning and test prep...

Your trachea -- in the upper respiratory tract -- is lined by a pseudo-stratified columnar epithelium with goblet cells.
There are no alveoli in the conducting zone (therefore no gas exchange, therefore, it's a dead space).
Your respiratory zone contains 2 types of lung cells (pneumocytes):
- Type 1 pneumocytes: squamous epithelium, for gas exchange.
- Type 2 pneumocytes: cuboidal epithelium, for secreting surfactant...It's also a stem cell responsible for regeneration.

At 9:05 isn't it it supposed to be that alkalosis results in a low pco2 but a high bicarbonate and that acidosis causes a high pco2 (thereby higher [H+]) and a low bicarbonate?
