Cockroaches have spiracles on the underside of their abdomen which draw in air which is then distributed to the the small adjacent chamber called the atrium. Stigmata bears limit the entry of dust into the tracheal system.
The air then moves out of the atrium to the connecting trachea which carry the air directly to the cells fro gas exchange to occur
stomata
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
Respirtary system, lungs, also known as thoratic region
Gaseous exchange takes place in the lungs, specifically in the alveoli. Oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled.
Because they have a greater surface area over which gaseous exchange can take place.
Gaseous exchange in humans takes place in the alveoli of the lungs. Oxygen from inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
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.
In lower plants such as mosses and liverworts, gaseous exchange occurs through simple diffusion across the cell membranes. These plants lack specialized structures like stomata found in higher plants, so gases enter and exit the plant cells directly through their surfaces. This process is limited by the surface area available for exchange, making lower plants reliant on moist environments for efficient gaseous exchange.
