Alveoli A scanning electron micrograph reveals the tiny sacs known as alveoli within a section of human lung tissue. Human beings have a thin layer of about 700 million alveoli within their lungs. This layer is crucial in the process called respiration, exchanging oxygen and carbon dioxide with the surrounding blood capillaries.
