What is the primary factor that maintains the pressure gradient that drives oxygen from the capillaries into the interstitial spaces and into the cells?

Question

Quizplus · Accepted Answer

Cellular consumption of oxygen creates a lower partial pressure of oxygen within the cells compared to the capillaries, creating a pressure gradient that drives oxygen diffusion from the capillaries into the interstitial spaces and ultimately into the cells. The other options (Bohr effect, Haldane effect, and carbon dioxide levels) may affect the binding and release of oxygen by hemoglobin, but they do not directly maintain the pressure gradient that drives oxygen diffusion.
