Blood Flow thru the Adult Heart


Blood Flow thru the Adult


Correct answer: Below is a detailed answer about the blood flow through the heart.

There is a possibility of 4 questions on the national exam that will be based on the information below.

Deoxygenated blood travels from the head neck and heart regions into the superior vena cava (SVC) and from the body to the inferior vena cava (IVC) into the right atrium (RA) and through the tricuspid valve into the right ventricle (RV), then through pulmonary artery (PA) to pulmonary capillaries of the lungs (to pick up oxygenated blood and get rid of carbon dioxide) then through the pulmonary vein (PV) back into to left atrium (LA) and through mitral (=bicuspid valve) valve into left ventricle (LV) then through aortic valve to the aorta and then to the heart itself (via coronary arteries), head/neck and the rest of the body via arteries then back to the heart via veins to the inferior and superior vena cava and back into right atrium. (Note: blood that feed the heart muscle itself via the coronary arteries, returns to the right atrium via the coronary sinus).

For the heart valves if you remember the follow saying:

" T ry before you B uy" then you will remember that blood through enters the T ricuspid valve (on the right side of the heart) before it goes through the B icuspid ( M itral) valve on the left side of the heart.
