The cardiac center, located in the medulla oblongata of the brain, regulates cardiac output primarily through autonomic nervous system control. It modulates heart rate and stroke volume by influencing the sympathetic and parasympathetic nervous systems; the sympathetic system increases heart rate and contractility, while the parasympathetic system decreases heart rate. Additionally, the cardiac center responds to various physiological signals, such as blood pressure and oxygen levels, to maintain adequate blood flow and ensure proper organ function. This dynamic regulation allows the body to adapt cardiac output to meet varying demands during rest and activity.
What else can I help you with?
Where in the body is the regulation of cardiac output centered?
The Cardiac Control Centre (CCC) is located in the brain, and controls the impulses created in the heart by the Synal Atrial node (SA node) as well as the impulses in the Atrioventricular node (AV node). The 'CCC' therefore controls systole in the atria and ventricles, and consequently heart rate is heightened or reduced based on the commands the Cardiac Control Centre gives out.
Amount of blood pumped by the heart in 1 min?
cardiac output :)

How intrinsic control mechanisms cause cardiac output to increase during exercise?
that means that she wants you
Determined by heart rate x stroke volume?
cardiac output
If resting cardiac output is six liters and maximum exercise cardiac output is sixteen liters what is the cardiac reserve?
10 liters
How much blood returns to the heart?
cardiac output
Which statement is correct about cardiac output?
cardiac output is heart rate multiplied by stroke volume,
What is resting cardiac output?
its not cardiac rest, its cardiac ARREST. which is a heart attack.
What is cardiac-output?
Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV.
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
