This happens by Diffusion
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.
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.
Help in gaseous exchange
Because alveoli have to be able to exchange gases freely like oxygen and get rid of carbon dioxide. Also, oxygen must have moisture to benefit breathing.
In the lungs.
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
Small organisms, like a amoeba's, have large surface area : volume ratios which means the exchange can take place by diffusion through the cell wall, the same as any other single celled organsism.
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.

The digestion of food in Amoeba takes place in the food vacuole. :)

The exchange of oxygen takes place in the alveoli. It is found in our lungs
