Question

Quizplus · Accepted Answer

The word "perfuse" in this context means to supply (an organ or tissue) with blood or other fluid, typically through vessels. Therefore, D is the best choice as it accurately describes how the inhaled air must meet up with the circulatory system to deliver oxygen to cells. Option A, "diffuse", is not the best choice as it describes the movement of molecules from high to low concentration and does not accurately capture the concept of air meeting up with the circulatory system. Option B, "hyperoxygenate", is not the best choice as it denotes adding more oxygen to the air than normal, which is not necessary for the air to meet up with the circulatory system. Lastly, option C, "register", is not the best choice as it refers to the process of recording or measuring something, which is not relevant to how air meets up with the circulatory system.
