It comes from the body when it containly exchanges throught the lungs.
Gaseous exchange
The process by which gaseous exchange occurs at the alveolar-capillary membrane is called external respiration. This involves the exchange of oxygen and carbon dioxide between the alveoli in the lungs and the blood capillaries surrounding them.
Gaseous exchange is the process of transferring oxygen from inhaled air into the bloodstream and removing carbon dioxide from the bloodstream into the exhaled air. This occurs in the alveoli of the lungs.
A gaseous exchange system refers to the biological mechanism through which organisms exchange gases with their environment, primarily oxygen and carbon dioxide. In animals, this process typically occurs in specialized structures such as lungs or gills, where oxygen is absorbed into the bloodstream and carbon dioxide is expelled. In plants, gaseous exchange occurs through stomata on leaves, allowing for the uptake of carbon dioxide for photosynthesis and the release of oxygen. This system is essential for maintaining cellular respiration and overall metabolic function in living organisms.
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.
Gaseous exchange is a natural process, ventilation is a forced process.

In earthworms the gaseous exchange takes place from their skin

Because to carry out the process of diffusion of gas.
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.
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
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
