Amoebas do not have lungs; they respire through a process called diffusion. Oxygen from their surrounding environment enters the amoeba's cytoplasm directly through its cell membrane, while carbon dioxide produced as a waste product diffuses out. This simple method of gas exchange is effective due to the amoeba's small size and large surface area relative to its volume, allowing for efficient absorption of oxygen and removal of carbon dioxide.
