... The other day we did an experiment which involved increasing the concentration of calcium and adding to the organ bath containing a strip of rat ventricular muscle...the results were that with higher concs. an increase in force was seen..just wondering is this due the the calcium induced calcium ...

... exposed the majority of the time. The systolic blood pressure, on the other hand, is exerted on blood vessels only in short bursts following the ventricular contractions. This observation led researchers to believe that a high diastolic blood pressure was the most important indicator of health ...

... transmission flows through the pathway of SA Node, atrial syncytium, junctional fibers, AV Node, Bundle of His, Purkinje fibers, and finally, ventricular syncytium - at what point along this pathway does ventricular depolarization actually begin? My answer is that it does not begin until after ...

... and nutrients. So the solution evolution found is deposit all the blood in the atria and keep it there. when the ventricles relax, the atrio-ventricular valves open and the blood flows according to gravity. the atria also contract, but the contraction is short(0.1 seconds) and inneficient. ...
