Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.
In lungs alveoli is present where exchange of gases takes place, when blood with carbon dioxide is reached lungs then these alveoli purify by removing carbon dioxide
The exchange takes place within the lungs.
Plants respire through tiny openings or holes called stomata that are present on the underside of the leaves. Stomata trap air (like oxygen) and the exchange of gases takes place in side the plant cells.
Gaseous exchange takes place in the alveoli in the lungs, Oxygen is inhaled while Carbon dioxide is exhaled.
The diffusion of gases takes place from their higher concentration to lower concentration. Exchange of oxygen by carbondioxide is the usual feature of breathing by lungs.
gaseous exchange - in the alveolis
stomata
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
gaseous exchange in the lungs takes place in the walls of the alveoli which are provided with a rich supply of blood vessels .the partial pressures of the gases .i.e. CO2 and oxygen in the atmosphere and the blood vessel is naturally perfect for the diffusion of gases.
This happens by Diffusion
In the alveoli
they use their stomata to exchange gases with the environment by taking in carbon dioxide and releasing oxygen and water vapor into the air
Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.
In earthworms the gaseous exchange takes place from their skin
Diffusion.
