Humans are much larger so they have small surface area which creates a greater distances to move the oxygen (O2) & carbon dioxide (CO2), so a special respiratory surface (LUNGS) is needed as well as an internal transport system (CIRCULATORY SYSTEM).

∙ 13y agoGas Exchange is necessary because when you inhale, the High concentration of oxygen will diffuse through alveolar and capillary wall into the blood where there is low concentraion of Oxygen to supply the cells. (Remember, any particle will always go from High --> Low)
Same concept when you Exhale, the High concentration of Carbon dioxide diffuse through the walls into the lungs where there is a low concentration of CO2.
This is a brief explaination; hope it helps.

How can leafs exchange gases in the absence of light?
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
Gas exchange is also known as?
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
When checking the efficiency of gas exchange it may be necessary to draw a blood sample from where?
Am artery
Why are transport systems necessary in multicellular plants and animals?
to maintain proper metabolism, mainly gas exchange
Why it is necessary for the lungs to have a dense capillary network?
Because it speeds up the gas exchange because it has a larger surface area.
Is gas exchange a function of the digestive system?
Gas exchange is a function of respiration not digestion.
What is the elastic unit of the respiratory system where gas exchange occurs?
Alveoli is where gas exchange occurs.
What effect does emphysema have on the total area available for gas exchange?
It lowers the area available for gas exchange, therefore gas exchange doesn't happen as quickly or as much as it should.
What system provides gas exchange between blood and air?
Capillary system is where gas exchange occurs
What do gas exchange systems have in common?
The exchange surfaces are moist.
What is the name for exchange of gas in the lungs?
gaseous exchange
In which structure does gas exchange occur?
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
