- How does the structure of alveoli maximize gas exchange?arrow_forwardWe inhale oxygen when we breathe and exhale carbon dioxide. What is the oxygen used for and where does the carbon dioxide come from?arrow_forwardExplain why the gas values from the alveolar air to the blood change during pulmonary gas exchange. For example: Alveolar air for CO2 has a value of 40mmHg then when entering the blood shifts to 45mmHg. Why does this occur? I tried to calculate this by using Dalton’s law but I’m not Understanding.arrow_forward
