WebHowever, as we all know, our heart rate, and hence cardiac output, changes dramatically depending on our activities. Some of these changes are due to mechanisms built into the heart itself, intrinsic regulation, and others are affected by the nervous and/or endocrine system, extrinsic regulation.
