CARDIAC OUTPUT

(View Complete Item Description)

Introduction: Vertebrate circulatory systems consist of blood, which transports materials to and from cells via blood vessels, and a heart to pump the blood. One important role of the circulatory system is to provide oxygen to cells. As a general rule, small animals have a higher rate of oxygen consumption per unit body mass than large animals. Therefore, the heart of a small animal must supply oxygen at a higher rate than the heart of a large animal. Since the oxygen capacity of blood is similar between small and large animals, small animals must have hearts that pump blood at a higher rate, or in other words, have a higher cardiac output. Question: How do changes in stroke volume and heartbeat frequency affect cardiac output?
