Question

deoxygenated blood in heart is carry by ,and why

Answer 1

It is best to think of veins as being vessels that go into the heart (bringing deoxygenated blood in normally and oxygenated blood in after a trip to the lungs) and arteries as going out (out to the rest of the body with oxygenated blood usually and out to the lungs to oxygenate blood).

So, to conclude, veins almost always carry deoxygenated blood, unless they lead to the heart from the lungs (pulmonary vein).

Hope this helps; let me know if I can do anything else or if anything needs clearing up:)

thnx dear for this question❤❤
