Define external respiration, gas diffusion, and internal respiration
What will be an ideal response?
External respiration is all the processes involved in the exchange of oxygen and carbon dioxide between the blood, lungs, and the external environment. Gas diffusion is the movement of O2 and CO2 across the blood air barrier between alveolar air spaces and alveolar capillaries and across capillary walls between blood and other tissues. Internal respiration is the absorption of O2 from blood and the release of CO2 by tissue cells.
