Question

Quizplus · Accepted Answer

Oxygen consumption, cardiac output, and blood oxygen content are interrelated. Oxygen consumption determines the amount of oxygen needed by the body, which affects cardiac output. Cardiac output is the amount of blood pumped by the heart per minute, which affects the delivery of oxygen to the tissues and the blood oxygen content. Therefore, these variables are not unrelated.
