Assalamo Alaikum.

about the distribution of structural featues in gaseous exchange parts:
im my book it says that there are no goblet cells in bronchiole.
while in the question paper 2010 http://www.xtremepapers.net/CIE/Interna ... _qp_22.pdf question 5 shows that (C) which is a bronchiole has goblet cells. -_-
can someone please clear out that for me please?
thanks.

When i did the topic,my teacher told me that goblet cells are not present in bronchi oles.Even in the Book of S.Soper it is stated..

 

[larina]

but i asked my teacher today, she said that mucus is produced by the bronchioles so it must have goblet cells :S
anyways im gonna ask her again.

it does have goblet cells! the name might be different but the goblet cells are there and it produces mucus. some substance in smoke stops these cells from working.

 

[larina]

but if u refer to the biology book frm cambridge by mary jones, it says that there are no goblet cells in the bronchiole.

yes larina you are right ,in mary jones , it do states that there are no goblet cells in bronchiole but the opposite is true in sooper .
As a advice , i would recommend you to go with mary jones as it is the CIE endorsed book written by examiners and used by examiners in formulating the paper ..

Bronchioles have goblet cells and that' confirmed via other different books. However, I don't understand why Mary Jones doesn't say so ... :s
