True or False';Great vessels are those that directly come from of go into the heart.?

Well from my training in cardiovascular medicine. The answer would be true with a caveat.


Blue blood vessels, the inferior and superior vena cava taking deoxygenated blood to the right heart which is pumped through the Pulmonary Artery to the lungs to turn into oxygenated red blood in the lungs alveolar/capillary network and returned via the Pulmonary veins (of which there are four) that dump into the left heart, specifically the left atrium. Then pumped out the left ventricle to the greatest of vessels to the body via the Aorta.


So you have this list of the great vessels:


Superior and Invferior Vena Cava


Pulmonary Artery (which splits into the right and left to go to each respective lung)


4 Pulmonary veins (all just dump into the left atrium, 2 from each lung)


Aorta.





Great vessels can also refer mainly to the pumonary artery and aorta which can be transposed at birth in an embryological mishap which is the most common use of the term ';great vessels'; called of course, transposition of the great vessels referring almost exlusively to the pulmonary artery and aorta in the commonest form but can mean any of the vessels listed above.. Soooo, the term great vessels includes all the vessels that go into and out of the heart with the exceptions of the coronary sinus and coronary arteries which supply blood flow to the heart itself. They are great indeed, coronary arteries if clogged cause heart attacks. But great vessels are what the heart dangles from basically, not referring to its own blood circulation. So it could be construed as a bit of a trick question or poorly written as the coronary arteries and coronary sinus go into and out of the heart. Well the coronary arteries come off within millimeters of the take of the aorta.





Hope that helps,

great vessels is such an ambiguous term!


directly into and out of your heart are:





right atrium: vena cava (superior, inferior)


right ventricle: pulmonary artery


left atrium: pulmonary vein


left ventrical: aorta





i guess TRUE because those seem pretty great to me!True or False';Great vessels are those that directly come from of go into the heart.?
Huh- I always thought ';great vessels'; are the large ones, the aorta, and the vena cava. So, not all the vessels mentioned would be ';great';.





Maybe you should try wiki or one of the family doc sites!
true--aorta, superior vena caeva and inferior vena caeva
