And their answer key to look at
click on the video below to observe a beating heart. NOTE which valves shut during the lub, dub sound and observe whether the heart is contracting or relaxing during the heart sounds. Slow down the video of you have to
ADVANCED LEARNING: ACTION POTENTIAL AND VECTORS:
If you are interested in a more advanced understanding of the cardiac conduction system, this website is an excellent source that goes into detail on resting potential and action potential in myocytes. Here is a very advanced tutorial on electrical vectors of the heart
This part is part of our curriculum (below) :
It is a very good video explaining the
CARDIAC CONDUCTION SYSTEM:
Finally, an excellent view from above showing how the systole and diastole synchronize together. The letters stand for valves: M is mitral, T is tricuspid, A is Aortic and P is pulmonary. where you see the word "squirt", it indicates ventricular contraction. Where you see "fill" is the atrial contraction.
