What is adenosine and why does its blockage cause the heart to pound?

I'm doing an experiment write up about the affects of caffeine on a daphnia's heart rate. Apparently, one reason for this, is that caffeine blocks adenosine receptors on heart muscle cells, which causes the heart to pound. What exactly is adenosine and why does its blockage cause the heart to pound?? Thanks in advance.
