Document Summary
Through the pulmonary circuits (to and from the lungs) nunidea(cid:12200)chas oz) Through the systemic circuits (pumps oxygenated blood around the body) Transport system pump, blood vessel are the delivery system. R atriuum; gets oxygen poor blood to r ventricle to lungs ; to l atrium (now oxygen rich) to left ventricle; pumped throughout the body. Tough dense, connective tissue that a) protects the heart and b) anchors it to surrounding structures and c) prevents heart from overfilling with blood. Forms an enclosed sac around the heart ayvpgceral pericardium to move freely (cid:8869) b)parietal pericardium. From atrium to ventricle then to the lungs or the rest of the body. L side is systemic circuit pump (oxygen poor) R side is pulmonary circuit pump (oxygen rich) Ra- rv-lungs- (carried through two pulmonary arteries)- back to the heart, when oxygen rich (carried through four pulmonary veins) From the heart > la > lv> aorta> to the body and repeats oxygen rich*
