message: My understanding was that the CO2 exchange was based on sodium bicarbonate and that carbon dioxide does not bind to red blood cells. Perhaps this can be checked and this page updated? CustardJack — Preceding undated comment added 13:06, 8 April 2005 (UTC)
replies: text: No, only 70% of CO2 is exchanged to sodium bicarbonate. Roughly 23% binds to hemoglobin. The remaining 7% travels dissolved in the plasma.— Preceding unsigned comment added by Blyndon (talk • contribs) 06:10, 13 May 2005 (UTC)

message: Is there a disease in which the alveolus don't work because the gas exchange is only one way? It is said it is something irreversible. Is there a name for this disease?

thread_title:  Typing error under 'Chronic bronchitis'? 

message: This looks way too small, if the 0.1 mm (100 micron) radius is correct, the photomicrograph indicates that the walls would be about 10-20 microns thick. Mammalian cells are bigger than 0.2 microns, usually 10-20 microns at least. (Bacterial cells are 1-2 microns in size) Furthermore, the alvelolar walls contain capillaries through which erythrocytes (radius 6-8 microns, thickness 1-2 microns) pass.   Please clarify -- Thanks! susato 14:46, 26 September 2007 (UTC)

message: Problem: When i wikipedia "alveolar sac" im redirected to alveolus, however these two are not the same.  Dorland's defines alveolus as, "... small polyhedral outpouchings along the walls of the alveolar sacs and alveolar ducts" and therefore "alveolar sac" would consist of the chamber directly preceding the alveolus.  —Preceding unsigned comment added by Lasse9477dkimedepauw (talk • contribs) 12:24, 26 March 2010 (UTC)
thread_title:  redirection error? 

message: With reference to number of alveoli:  text books (GCSE/O level textbooks and A level text books) quote a TOTAL of 300-350 million alveoli in both lungs NOT each in lung.  Total surface area of 90-100m2 does agree with text books.  Just wanted to put forward this point.  Maybe someone might clarify.  —Preceding unsigned comment added by 85.232.213.63 (talk) 13:22, 13 February 2011 (UTC)

message: As indicated by the many entries at Alveolus (disambiguation), this is not the only, or even main, meaning of the word. Therefore those terms should not redirect here. FunkMonk (talk) 11:56, 20 March 2018 (UTC)
replies: text: Hello FunkMonk - there is a hatnote on the page to refer to Disambig page for other uses. It may be the most searched for ? --Iztwoz (talk) 14:32, 7 June 2018 (UTC)
replies: text: That doesn't explain why those terms should redirect here. FunkMonk (talk) 18:51, 7 June 2018 (UTC)
replies: text: FunkMonk Have looked again and tend to agree with you - have changed redirect to the disambiguation page - If alveolus was to redirect to pulmonary alveolus then pulmonary alveolus ought to be the primary topic and named alveolus. However I left alveoli as it's the usual plural? --Iztwoz (talk) 20:22, 22 June 2019 (UTC)
replies: text: But have just looked at disambiguation page and there are other terms that use the plural so shall go ahead and change that redirect. best--Iztwoz (talk) 20:25, 22 June 2019 (UTC)
thread_title:  Alveolus/alveoli shouldn't redirect here 

message: "They are located sparsely on the respiratory bronchioles, line the walls of the alveolar ducts, and are more numerous in the blind-ended alveolar sacs."
Is this really saying that there are alveoli elsewhere than in the alveolar sacs? If so is there a source for this information? It contradicts what is shown in the diagram, and what every independent source I can find says about the subject, to the extent that I wonder if the sentence has been taken out of context and "they" is not actually supposed to refer to alveoli - for example it would make sense if it was about capillaries.

replies: text: Pulmonary alveolus →  – There is no page at the moment which is often referred to, and since all alveoli make up the parenchyma, new page would be a good parent page. It would easily also be a better target for other structures at the moment included in Pulmonary alveolus page such as alveolar ducts, and sacs. Iztwoz (talk) 20:30, 12 September 2021 (UTC)

text: Hi Iztwoz, I respectfully disagree with this move proposal. Pulmonary alveolus is in my mind an independently notable concept worthy of an encyclopedic article that I think many readers will be searching for individually. If we do need a lung parenchyma article in my opinion we should call it Lung tissue for consistency with other articles. Tom (LT) (talk) 07:50, 14 September 2021 (UTC)
replies: text: Thanks Tom! Lung tissue would absolutely be the better page. It would have to feature most of the alveolus page but suppose that would work.--Iztwoz (talk) 09:22, 15 September 2021 (UTC)

message: In the section "Clinical Significance", subsection "Surfactant", third sentence, it reads:
"The severe condition of acute respiratory distress syndrome (ARDS) is caused by a deficiency or dysfunction of surfactant".
According to the reference 26 cited right after, that is not true. While ARDS is accompanied by deficiency or dysfunction of surfactant, this is not the cause for ARDS. Rather, several heterogeneous conditions cause ARDS, which has surfactant dysfunction as one of the mechanisms responsible for some symptoms like atelectasis and difficulty breathing. 168.197.244.246 (talk) 12:56, 15 May 2024 (UTC)
