What is cardiac output?
Understand the Problem
The question is asking for information about cardiac output, which is a key concept in physiology. It refers to the volume of blood the heart pumps per minute and is an important measure of heart function. The question likely seeks to understand what cardiac output is, how it is measured, and its significance in the context of health and disease.
Answer
Cardiac output is the volume of blood the heart pumps per minute.
Cardiac output is the volume of blood pumped by the heart per minute, typically calculated as the product of heart rate and stroke volume.
Answer for screen readers
Cardiac output is the volume of blood pumped by the heart per minute, typically calculated as the product of heart rate and stroke volume.
More Information
Cardiac output provides essential insights into heart health by indicating how efficiently the heart can supply the body with blood. It varies with factors like heart rate, stroke volume, and physical condition.
Tips
A common mistake is confusing cardiac output with stroke volume. Remember, cardiac output is the total blood volume pumped per minute, which is heart rate multiplied by stroke volume.
