How does the oxygen enter your heart?

Highly oxygenated blood enters the heart via the pulmonary veins into the left atrium of the heart. Veins return to the heart and normally have relatively deoxygenated blood (pulmonary veins are an exception to this rule and have freshly-oxygenated blood) while arteries go away from the heart and have highly oxygenated blood (the pulmonary artery bringing blood from the right ventricle toward the lungs is an exception and has poorly oxygenated blood).


When deoxygenated blood leaves the heart where does it go?

Freshly oxygenated blood from the lungs goes directly to the heart. From there, approximately 50% of the blood goes directly to the brain and head while the other half is distributed to the rest of the body.


Why the blood vessel that carrying oxygenated blood from lungs is a vein while the the other vessels carrying oxygenated blood are arteries?

It differs in pulmonary arteries and veins because they do the opposite thing to normal arteries and veins. Arteries usually carry oxygenated blood away from the heart to the body but pulmonary means lungs and the pulmonary artery carries de-oxygenated blood away from the heart but to the lungs and not round the body. Veins usually carry de-oxygenated blood back to the heart but the pulmonary vein carries oxygenated blood to the heart which then pumps it into the aorta which takes it to the body. bla bla bla

When you consider oxygen and de-oxygenated blood.The pulmonary veins are large blood vessels that carry oxygenated blood from the lungs to the left atrium of the heart.The pulmonary arteries carry deoxygenated blood from the heart to the lungs.


What vessels transports oxygenated blood from the lungs to the left atrium?

The pulmonary vein. Veins go to the heart, arteries come out. Even though the blood is oxygenated, it still travels through a vein to get to the heart. I'll leave it to you to figure out the pulmonary artery.
