Question

Quizplus · Accepted Answer

Gas movement in biological systems, such as in the human body, primarily occurs down its partial pressure gradient. This is a fundamental principle in respiratory physiology, where gases like oxygen and carbon dioxide are exchanged between the blood and lung air spaces based on differences in partial pressures.
