Questions & Step-by-Step Solutions
Which of the following factors can increase cardiac output?
Step 1: Understand what cardiac output is. Cardiac output is the amount of blood the heart pumps in one minute.
Step 2: Know the two main components of cardiac output: heart rate (how many times the heart beats in a minute) and stroke volume (the amount of blood pumped with each beat).
Step 3: Remember the formula for cardiac output: Cardiac Output = Heart Rate x Stroke Volume.
Step 4: Realize that if you increase the heart rate, while keeping stroke volume the same, the cardiac output will increase.
Step 5: Consider other factors that can also increase stroke volume, such as exercise or increased blood volume, which can also lead to higher cardiac output.
