In fact, the difficulty of gas exchange as single-celled organisms get larger is a factor which leads to larger organisms being multicellular. Insect Gas Exchange
WebGas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs. Alveoli are in direct contact with capillaries (one-cell thick) of the circulatory system.
