Histopathology Lung--Emphysema

[WashingtonDeceit]

Thank you!

First, your videos have helped me immensely. Thanks!

In the video you say that the reason for alveolar wall destruction destruction is due to increased airway resistance upon expiration. Although this may contribute to the problem, the dominant paradigm of emphysema pathogenesis, the protease-antiprotease theory, states that the production of proteolytic enzymes by inflammatory cells combined with a decreased ability to break down these proteases leads to alveolar destruction.

good video. Thanks.

this video is straight up misleading. emphysema is not synonymous with copd. copd is an umbrella term included emphysema and chronic bronchitis. alveoli may burst, and may burst due to increased intra-alveolar pressures secondary to attempted expiration with obstruction, but certainly this isn't the major histopathological feature. alveoli lose their elastase and become floppy, upon expiration the angled walls of the alveoli do not have the elastic recoil to remain open, so they collapse

@bmwmaniac1 , forming an obstruction. alveolar dilation is the majro histopathological feature. some interesting sequela were brought up, but i do not feel this gives a good overall picture.

thanks... liked it a lot

Thanks from me too.

wat makes it called as "pink puffer"

[MaMa8403]

The term "pink puffer" is used to differentiate the clinical manifestation of emphysema and chronic bronchitis (blue bloater). With emphysema, pink puffers are fighters. They develop a reddish pinkish complexion and expiration is accomplish thru pursed lip (puffer) breathing which increase respiration to maintain oxygen levels so that their lungs won't collapse.

Thanks a lott :)

very helpful

wats the pathophysiology of emphysema?

[montage03]

No, thank YOU!

That was great.
