Gas exchange explained
WebGas exchange is the physical process by which gases move passively, meaning that no energy is required to power the transport, by diffusion across a surface. External respiration is another term for gas exchange. WebJun 8, 2024 · Gas Exchange across the Alveoli In the human body, oxygen is used by cells of the body’s tissues to produce ATP, while carbon dioxide is produced as a waste product. The ratio of carbon dioxide production to oxygen consumption is referred to as the respiratory quotient (RQ), which typically varies between 0.7 and 1.0.
