Why would you have thought otherwise? Blood then flows from both upper atrium's (left atrium and right atrium) into the two lower chambers (left and right ventricles) which then expand. ECF & SR Calcium ions build up in sarcoplasm (latent period) & initiate contraction (EC coupling) Not all terms are used and terms may be used more than once. In your description, discuss the location of the autorhythmic cells and the importance of gap junctions in spreading the depolarization wave through the contractile cells of the myocardium. Blood passes through the aortic valve and into the aortic arch, which gives off several branches that distribute blood to all parts of your body.
