|
What cells secrete angiotensin converting enzyme
|
respiratory endothelial cells
|
|
|
Alveolar macrophages (AKA dust cells)
|
Pass freely between septum and alveolar lumen.
Also called heart failure cells. First line of air way defense. Outnumber all other cells. |
|
|
What do lamellar look like according to Dr. Meek, and what cells are they found within. What do these structures do?
|
Hay bales, type II pneumocytes. Lamellar bodies store surfactant!!
|
|
|
Are type I or type II pneumocytes more common.
|
type II are more prevalent
|
|
|
effectively secretory by week 31, Maturation determined by lecithin-sphingomyelin ratio, week 37 usually no problem, if problems, causes RDS
|
Type II alveolar cells
|

Which type of pneumocytes have a round nucleus??
|
Type II

|
What stains darkly in blood-thirsty alveolar macrophages, and what are the cells called with this debris
|
hemosiderin
heart failure cells |
|
|
What 3 things do alveolar macrophages use well to efficiently defend the lungs
|
acid phosphatase, Beta glucuronidase, and lysozyme concentrations
|
|
|
which cells have a nuclei that bulge into the alveolar wall, and which cells have a nuclei that bulges out into the airway
|
endothelial cells, type I pneumocytes
|
