1) Explain why alveolar gas has a different composition from air. Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary
