Question for pig dissection

Postby seasira » Thu Jun 01, 2006 12:22 am

Hi I am doing the pig dissection in school, and I need help on a question and I was hoping you guys could help.

In terrestrial vertebrates, what is the advantage of having the surfaces for oxygen and carbon dioxide exchange embedded in deep lung tissue?

Its not in my packet anywhere Thank you so much. If I find the answer before there are any posts I will let you know.

these serves as protection from the various pathogens,before the inhaled air can enter the body, the immune mechanism like the respiratory cilia, mucus can hinder the entry of bacteria and viruses.

you are right, docbandoodles, especially in humans. But in amphibians for example, most of these adaptations do not occur. As Dave said, the main problem is water loss...
