Re: How is cardiac output controlled by the autonomic nervous system?

Hi, Cardiac Output is defined as being the volume of blood ejected by one 
ventricle in one minute.

The Cardiovascular system is ultimately controlled by the autonomic nerves.
Arterial stretch receptors or baroreceptord are located in the carotid 
sinus and the aortic arch, they play a key role in blood pressure control 
and respond to stretch of the vessel wall. They produce impulses at normal 
vessel tone, if stretch increases due to increased pressure then the 
impulse firing rate will rise likewise it will fall if the stretch 
decreases. An increase in firing rate causes a decrease in heart rate 
initiated via the medulla it also causes a drop in resistance. The idea of 
these baroreceptors is to buffer the blood pressure in the short term.
