Examples of surfaces for the exchange of substances in animal organism
transport systems
Doc Brown's biology exam revision study notes
For plants see
Transport
in plants notes,
BUT first read
Diffusion, osmosis and active transport then this page
This page will help you answer questions
such as ...
Why do exchanges surfaces need to be
large? In what way are organs designed to have
large surface areas?
How does transportation of materials through membranes take
place?
Sub-index for these pages on exchange surfaces in organisms
1.
A mathematical 'extra' on
surface area to volume ratio calculations and implications for exchange
surfaces in living organisms
2.
Introduction to exchange surfaces in cells and
organs
3.
Gas exchange in
the human lungs by diffusion - extra comments on breathing, COPD and ventilators
4.
Gas exchange and the structure of fish gills
5.

surface of the small
intestine
6.
