Document Summary

Fick equation: v02 = hr x sv x (a-v02diff) The cardiovascular system: how much blood volume someone has in their system depends on their size, but generally, blood volume at rest. It requires blood flow and oxygen; needs to have co2 removed: there are right and left coronary arteries; Posterior and anterior interventricular arteries; circumflex artery (like a belt going around the heart: myocardial infarction (aka. Initiation of heart contraction and relaxation: the heart beats rhythmically 24/7, sa node cluster of cells in the right side of the atria. Initially, the depolarization will move through the septum, then the apex of the heart, then the tissue of both left and right ventricles. Look at example in the picture: ejection fraction, the portion (percentage) of your edv that you are pumping out. In the picture example, it is 60: ef = sv/edv x 100, cardiac output (q or co) volume of blood pumped out per minute in l.
