The human heart is an involuntary muscle that consists of four chambers: two atria and two ventricles. Its function is to transport oxygen-rich blood throughout the body via the circulatory system, nourishing and energizing living cells. Like any other muscle, the heart can be strengthened with exercise or weakened by a lack of physical activity.
Cardiac output is a function of stroke volume and heart rate. An individual's cardiac output can be determined by measuring the total volume of blood that is pumped by a heart ventricle (stroke volume) each time the heart beats (heart rate). The stroke volume multiplied by the heart rate equals cardiac output.
A simple mathematical equation is used to calculate the cardiac output of the heart, measured in milliliters per minute.
Cardiac Output in mL/min = heart rate (beats/min) X stroke volume (mL/beat)
An increase in stroke volume or heart rate of any intensity increases cardiac output.

If resting cardiac output is six liters and maximum exercise cardiac output is sixteen liters what is the cardiac reserve?
10 liters
Amount of blood pumped by the heart in 1 min?
cardiac output :)
How much blood returns to the heart?
cardiac output
What can decrease the cardiac output?
The cardiac output can be decreased by decreasing the force of contraction of the ventricular myocardium and decreasing the heart rate.
Amount of blood leaving a ventricle each minute is the?
Cardiac output
If resting cardiac output is six liters and maximum exercise cardiac output is sixteen liters what is the cardiac reserve?
10 liters
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
What effects cardiac output during the first few stages of exercise?
Cardiac Output is computed as your heart rate times your stroke volume (volume of blood ejected from the heart each beat). The main contributor when exercising is an acceleration in heart rate. Stroke volume can be increased, but only by prolonged aerobic training. To answer your Q, HR as has the main effect on cardiac output during the first stages of exercise.**The first few stages of cardiac exercise will 'affect' cardiac output, not 'effect' it. If you don't know the difference between the two, you should not be asking a question such as this...
What is the effect of cardiovascular excerise on cardiac output?
Cardiac output is the total volume of blood that is pumped by the heart per minute. When you exercise, there is a greater demand for oxygen, which is carried in your blood, thus your cardiac output increases.
Does cardiac output affect urine output?
Certainly. Decrease cardiac output would mean a decreased in blood flow to the kidneys, which would lead to reduced filtration, therefore urine output.
Does Exercise benefit the cardiovascular system?
Yes. Cardiac output is increased by any form of aerobic exercise.
How does positive-pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How does positive pressure ventilation affect cardiac output?
It increases intrathoracic pressure which decreases venous return to the heart and causes a decrease in cardiac output.
How intrinsic control mechanisms cause cardiac output to increase during exercise?
that means that she wants you
What is the effect of exercise on cardiac output and How would the fitness instructor measure the effect of exercise on the heart?
I don't have a trainer, I just do it alone
How does tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
