Final Answer:
The volume of blood ejected by each ventricle in one minute is called the E. Cardiac Output.
Step-by-step explanation:
Cardiac Output refers to the volume of blood ejected by each ventricle in one minute. It is a crucial physiological parameter that represents the efficiency of the heart in pumping blood throughout the circulatory system. Cardiac Output is calculated by multiplying the stroke volume (the amount of blood ejected with each heartbeat) by the heart rate (number of heartbeats per minute). The formula for Cardiac Output (CO) is CO = Stroke Volume (SV) × Heart Rate (HR).
Cardiac Output is a dynamic measure that reflects the heart's ability to meet the body's demand for oxygen and nutrients. Stroke Volume is determined by factors such as preload (the volume of blood in the ventricles before contraction), contractility (the force of ventricular contraction), and afterload (the resistance the heart must overcome to eject blood). Changes in heart rate and stroke volume can influence Cardiac Output, making it a valuable indicator of cardiovascular function.
In summary, Cardiac Output is a comprehensive measure that integrates both the mechanical and rate aspects of heart function. Monitoring Cardiac Output is essential in assessing cardiovascular health and understanding how well the heart is adapting to physiological demands.
Correct option is E. Cardiac Output.
