Cardiac Output Control Mechanisms

An increased venous return will result in an increased end diastolic volume, which causes a rise in ______

An increase in sympathetic activity or epinephrine will stimulate an increased contractility, which will in turn cause an increase in ______

A decreased arterial pressure or low afterload will cause an increased ______

An increased activity of the sympathetic nervous system to the heart will cause both an increased stroke volume and heart rate (because of increased contractility), which will result in an overall increase in ______

A decrease in the activity of the parasympathetic nervous system will cause an increased ______
