A discussion of the microscopic structure of the lungs, including the respiratory epithelium of the upper airways, and the different components of the alveoli (e.g. type 1 & 2 pneumocytes, alveolar-capillary membrane). Also discussed are the roles of collagen and elastin, and the difference between the lung interstitium and lung parenchyma.
0:00 Introduction
1:14 Conducting zone (i.e. respiratory epithelium)
4:32 Respiratory zone (i.e. alveoli)
8:39 Proteins of the extracellular matrix (e.g. collagen, elastin)
10:25 Lung interstitium vs. lung parenchyma
13:15 Summary
