amount of air that always remains in lungs sum of anatomical and alveolar dead space amount of air moved into and out of lung with each breath. space occupied by nonfunctional alveoli consists of air that remains in passageways amount of air that can be inspired forcibly beyond the tidal volume amount of air that can be forcibly expelled from lungs

The continuous exchange of gases between the blood and alveolar air in the lungs results in a partial pressure of ________. nitrogen in the alveoli that is higher than in atmospheric air carbon dioxide in the blood that is lower than in the alveoli oxygen in the alveoli that is lower than in atmospheric air water vapor in the alveoli that is lower than in atmospheric air carbon dioxide in the alveoli that is lower than in atmospheric air

In air is inhaled through the nasal and oral cavities (the nose and mouth). Air moves through the pharynx, larynx, and trachea into the lungs. Then, it is exhaled, flowing back through the same pathway. Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called . This respiratory process takes place through hundreds of millions of microscopic sacs called . The bloodstream delivers oxygen to cells and removes waste carbon dioxide through .
