How is cardiac output (CO) defined?

The amount of blood pumped from the left ventricle in one beat
The amount of blood pumped from the heart in one minute
The amount of blood remaining in the heart after a beat
The total blood flowing in the arteries

The correct answer is: The amount of blood pumped from the heart in one minute

Cardiac output is defined as the amount of blood that the heart pumps in one minute. It is a crucial measure of the heart's efficiency and overall cardiovascular health. The calculation of cardiac output is typically derived from the heart rate (the number of beats per minute) and stroke volume (the amount of blood pumped by the left ventricle per beat). When these two components are multiplied, they provide the total volume of blood that the heart ejects into the systemic circulation every minute. This measure is critical in assessing how well the body is being perfused with oxygen and nutrients, which can vary significantly with exercise, heart disease, and other conditions. Understanding cardiac output gives insight into overall cardiac function and can help guide training and rehabilitation protocols for individuals.
