,Efficiency of gaseous exchange surfaces in living organisms (aquatic and
terrestrial)
All organisms, from simple unicellular to complex mul
rely on gaseous exchange for survival. The amount of
up and CO2 released depends on :
• the ratio of surface area to volume of the organism
does this mean?
• Surface area is the combination of all the exposed
of the organism.
• The volume is the space taken up by the same org
• Therefore, the surface area to volume ratio would b
amount of surface an organism has relative to its s
In general, the smaller the organism the larger the sur
to volume ratio
,Relationship between respiratory structures and efficient gaseous exchange in different organisms
,The human gas exchange system consists of the following distinct sections:
air passages
lungs
muscles involved in the mechanism of breathing (ventilation)
The system is well designed to carry out the function of gaseous exchange. The images below show parts of t
respiratory system that are directly involved in breathing and gaseous exchange
