Question

Quizplus · Accepted Answer

The human lungs with many thin-walled alveoli have an increased surface area for absorption. This allows for efficient exchange of gases during respiration, including the absorption of oxygen into the bloodstream. The other choices do not necessarily involve absorption, and even if they do (such as the cow's digestive tract), they do not have an increased surface area for absorption.
