Cardiac Regulation

  • The pumping action of the heart must be finely regulated to meet physiological demands and is controlled by both intrinsic and extrinsic processes. The Frank-Starling Relationship describes an intrinsic regulatory mechanism of the heart which guarantees that the organ pumps out any blood that enters its chambers. Autonomic Regulation of the heart allows for the central nervous system to coordinate cardiac pumping with other, ongoing or anticipated physiological demands.
