Lungs do not collapse even after forceful expiration because of __________
Functional residual capacity is the volume of air remaining in the lungs
Compared to healthy individuals, the lungs' residual volumes of patients with emphysema is _______________
Greater because these patients lungs' air sacs (alveoli) are damaged to the point that air gets trapped, which increases their lungs' residual volume as well as the total lung capacity. However, these patients have problems oxygenating their blood because their damaged alveoli make them less able to absorb oxygen into the bloodstream and remove carbon dioxide from the blood.
Greater. With emphysema, the lungs become increasingly compliant, due to alveolar destruction. As the alveoli are destroyed, air is trapped in the lungs, and TLC is increased. This makes these patients be more efficient at absorbing oxygen into their bloodstream and remove carbon dioxide from their blood.
Smaller because these patients lungs' air sacs (alveoli) are damaged to the point that air gets trapped,ÿÿwhich decreases their lungs' residual volume as well as their total lung capacity. These…
