Final answer:
Stroke volume multiplied by heart rate and systemic vascular resistance equates to blood pressure (A). Cardiac output is the volume of blood pumped by the heart in a minute, calculated as heart rate times stroke volume, and is critical for adequate blood flow, particularly during exercise for maximum cardiac output.
Step-by-step explanation:
The formula provided in the question: Stroke volume (SV) × heart rate (HR) × systemic vascular resistance (SVR) correlates to blood pressure, not to the other options listed. Each factor plays a role in determining the overall blood pressure within the circulatory system (A). Option C, Cardiac output, is calculated by multiplying heart rate by stroke volume without considering systemic vascular resistance. Ejection fraction (B), which represents the percentage of blood pumped out of the ventricles with each beat, is calculated differently, by dividing stroke volume by end-diastolic volume (EDV). Lastly, end-diastolic pressure (D) is not directly calculated using this formula.
Cardiac output is a critical measurement that indicates the volume of blood the heart pumps out in one minute. It is important for maintaining adequate blood flow and pressure to meet the body's demands, especially during states such as exercise when maximum cardiac output is necessary.
