From the right atrium it goes into the right ventricle through the tricuspid valve. Through the pulmonary valve the blood travels into the pulmonary artery into the lungs where it picks up the oxygen it will need. The blood reenters the heart through the pulmonary veins and enters the left atrium. The blood then goes through the bicuspid (or mitral) valve into the left ventricle. Once in the left ventricle the blood goes through the aortic valve into the aorta. Once in the aorta the blood goes down into the left and right coronary arteries, which feed the lower part of the body and also up into the aortic arch and out through the brachiocephalic, common carotid, and subclavian arteries which feed the upper part of the body. Once the blood has been circulated throughout the body it comes back into the heart through the superior and inferior vena cavas and the process starts over again.<br />You asked for it. ;)Lois https://www.blogger.com/profile/15077488526424790807noreply@blogger.comtag:blogger.com,1999:blog-6295647504230837189.post-67987664079222346482012-03-15T15:22:26.032-05:002012-03-15T15:22:26.032-05:00Ok.
