Sergeeva-Olga [200]

Blood volume reflexes, hormones, body temperature, emotions, gender and age are the factors that affect cardiac output.

<h3>What are factors that can change cardiac output?</h3>

Factors that affect cardiac output are changing heart rate and stroke volume. Other factors include blood volume reflexes, hormones, body temperature, emotions, gender and age.

Heart sounds are created from blood flowing through the heart chambers when the cardiac valves open and close during the cardiac cycle.

Our heart sends the blood to the lungs, where it receives oxygen and dispose carbondioxide. Then, your heart pumps the oxygenated blood to the tissues and organs throughout your body.

So we can conclude that blood volume reflexes, hormones, body temperature, emotions, gender and age are the factors that affect cardiac output.
