What are the four major blood supplies?

Question

Four major blood supplies entering or exiting the heart? What could they be?

I have no idea what this question is asking... "There are four major blood supplies entering or exiting the heart. For each of these four areas, explain where the blood supply goes to or comes from, the name of the blood vessel carrying the supply, and where it enters or exits the heart."

Can anyone help me!!!

Thanks!

Answer 1

1.Blood in to right atrium from body via venae cavae.

2.Blood from right ventricle via pulmonary artery to lungs.

3.Blood in to left atrium from lungs via pulmonary vein.

4.Blood from left ventricle to body via aorta.

Answer 2

Blood full of CO2 LEAVING the heart through the pulmonary artery and going INTO the lungs

Blood full of O2 LEAVING the lungs and travelling INTO the heart through the pulmonary vein

Blood full of O2 LEAVING the heart through the Aorta and travelling to the rest of the body.

Blood full of CO2 LEAVING the body and travelling INTO the heart through the vena cava.

Answer 3

There is oxygenated blood which the heart pumps all over the body by the arteries, the blood that comes back to the heart through the veins is deoxygenated blood. Thats all i remember from anatomy visit the link below, it has great animation in explaining the heart.
