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 happens through diffusion.
gaseous exchange
Gaseous exchange is a natural process, ventilation is a forced process.
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
gaseous exchange - in the alveolis
Gaseous exchange in Amoeba occurs through diffusion. Oxygen from the surrounding environment diffuses into the cell across the cell membrane, while carbon dioxide produced by cellular respiration diffuses out of the cell. This process allows for the exchange of gases to support the metabolic activities of the cell.
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
