An increase in sympathetic stimulation of the heart would increase stroke volume by increasing view available hint(s) an increase in sympathetic stimulation of the heart would increase stroke volume by increasing end diastolic volume heart rate end systolic volume contractility submit

The equation for cardiac output is stroke volume x heart rate whereas stroke volume is the function of contractility. The correct answer is "contractility" is an increase in contractility will increase stroke volume. Sympathetic stimulation will also stimulate an increase in heart rate but this is wrong as an increase in heart rate will not increase the stroke volume but rather the overall cardiac output. The end systolic volume will also be increased by sympathetic stimulation but is unrelated to the stroke volume but rather in the heart rate (increase in heart rate results to decreased filling times leading to increased end systolic volume). End diastolic volume will be decreased as more blood goes out the heart per cycle as stroke volume (and cardiac output) increases.

You should provide a picture to show where the arrow is pointing and which information that is given. but there are 3 branches of the government, legislative, executive, and judicial. legislative makes laws, executives pass laws, and judicial are the courts
