WebTerms in this set (16) What is cardiac output, and how is it calculated? CO is the volume of blood that the heart ejects into the circulation each minute. It is the product of the heart rate (HR) and the stroke volume (SV-the volume of blood ejected during each beat). In humans, CO approximately 70 x 0.07=5.0 liters/min. WebFive liters would be a typical cardiac output, whereas a typical stroke volume would be 70 milliliters. Identify the cardiac measurements that will increase during exercise. Select all that apply.

More specifically, during aerobic exercise both heart rate and stroke volume increase to achieve a greater cardiac output.

Web1. During exercise, vagal activity diminishes and sympathetic activity increases. 2. Increased levels of circulating epinephrine. Both of these result in increased heart rate. WebThe enhanced cardiac output is distributed preferentially to the exercising muscles including the heart. Blood flow to the heart increases fourfold to fivefold as well, mainly reflecting the augmented metabolic requirements of the myocardium due to near maximal increases in cardiac rate and contractility.
