Intrinsic regulation of cardiac output

WebIntroduction: 1. The heart needs a lot of control mechanisms to allow it to perform its task of pumping blood reliably and adequately. 2. These control mechanisms can be classified into two groups: 1) Intrinsic regulation mechanisms. 2) Extrinsic regulation mechanisms. A. Intrinsic regulation: Sinus Node Stretch. 1. WebExcerpt. Although cardiac output is measured as the flow of blood from the left ventricle into the aorta, the system that controls cardiac output includes many other components …
