Some more insight into the differences between studying medicine and paramedics;
Paramedics - ..trachea, bronchus, bronchi -> terminal bronchi, alveoli.
Medicine - .... trachea, bronchus, bronchi -> terminal bronchi, - > acinus =respiratory bronchioles, alveolar ducts, alveoli.
Paramedics - Trachea/bronchus - cartilage rings, bronchioles - smooth muscle, alveoli - single-cell thick.
Medicine - Trachea/bronchus - cartilage ringes, pseudostratified ciliated columnar epithelium, goblet cells, bronchioles - smooth muscle, ciliated, Clara cells, alveoli - Type I pneumocytes, Type II pneumocytes, macrophages, PLUS name that histological picture(s)....
New thing I learned today - bronchioles are only <1mm in diametre! No wonder they get clogged up with secretions for poor people with asthma...
