The heart

Postby Drredfrizzle » Sun Nov 11, 2012 7:24 pm

I was just wondering, because I know that the heart can increase it's rate according to various stimuli what determines whether the heart increases the frequency of it's contraction or the strength of the beats/ stroke volume and does it vary depending on intensity of exercise ?
