|
Discribe blood flow through the heart
|
blood flows into R Atria through the tricuspid valve into the Right Ventricle and then pumped out through the pulmonary semilunar valve to the lungs via plumonary arteries. From the lung, blood returns via pulmonary veins into the L Atrium and through the mitrial valve into the left ventricle. From left ventricle, blood is ejected through the Aortic valve and into the Aortic arch. Blood then returns to the systemic system.

coronary arteries, supply blood to the myocardium
