What is surface area The total number of cells in direct contact witht the surrounding enviroment


What does surface area affect the rate of exchange of materials at exchange surfaces


What is volume the total 3 dimensional space taken up by metabolically active cells


What does an organisms volume/surface area the demand for metabolites
influence the rate of supply of metabolites to tissue


What happens as a organisms size increases and what The surface area to volume ratio decreases
is needed to combat this specialised exchange surfaces


How does a flattened shape helpm incraese gas by increasing the surface area to volume ratio so gas diffusion can ocurr
diffusion enough to meet metabolic demands


Examples of external exchange surfaces folded external membranes of gills in tadpoles


Examples of internal exhange surfaces fish gills
alveoli


Why is do land animals need internal surface exhange As a moist lining is needed for gas diffusion and land animals have a
impermeable body as not to lose water
