Oxygen travels into the smallest air sacs of the lungs, called alveoli. Capillaries around these air sacs allow blood to exchange oxygen for unwanted carbon dioxide. The oxygen-rich blood then returns to the heart to be pumped to the rest of the body. The carbon dioxide in the lungs is passed out of the body through the mouth and nose when we exhale.
So basically, your lungs have deoxygenated blood while the body has oxygenated blood.

Where does the blood that enters the atrium come from?
Oxygenated blood from the lungs enters the left atrium. The blood then moves from there to the left ventricle, aorta, and on the rest of the body.
Left ventricle lead to fluid in the lungs?
Left ventricle pumps oxygenated blood out through aorta and to the rest of the body. The right ventricle will pump deoxygenated blood to the pulmonary artery to get oxygenated in the lungs. Then the oxygenated blood will come back down the pulmonary vein into the left atria, and then left ventricle. The blood never fills up the lungs, the gas exchange occurs within the capillaries in the lungs.
A drop of blood in the pulmonary artery is oxygenated or deoxygenated?
Deoxygenated, the blood has come from the rest of the body to the heart via veins, and is being pumped from the heart (hence being an artery) to the lungs to be oxygenated, and brought back to the heart through the pulmonary vein as oxygenated blood (to be pumped to the rest of the body again).
What veil does oxygen blood come in and out?
Oxygenated blood is carried by the pulmonary vein. This vein transports blood from the lungs to the heart.
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
What is the name of blood vessel that takes blood 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.
What does the pulmonary vein do?
Carries oxygenated blood from the lungs to the left atria of the heart. Brings blood from the lungs to the heart.
Where does the blood in the left atrium come from?
It comes from the 4 pulmonary veins that drain into the left atrium. they carry oxygenated blood that has come from the pulmonary circulation as well as the deoxygenated blood from the bronchial arteries.
Where does blood entering the left auricle come from?
The blood in the left atrium comes from the pulmonary vein, that is, from the lungs. It's oxygenated blood, innit? The blood in the right atrium comes from the vena cava (either superior or inferior) which actually takes deoxygenated blood from the body into the heart, where it is later sent to the lungs for oxygenation... and so on.
What organ must blood go through in order to come back to the heart oxygenated?
Your heart gives oxygen to blood cells, then those carry oxygen throughout your body, and when they reach your heart again, it refills them with oxygen.
Were does the blood come from the right ventricle?
Blood flows into the right ventricle from the right atrium. The right ventricle will contract and pump the blood out to the lungs via the pulmonary veins to get oxygenated.
Blood flows from the left atrium to where?
The blood enters the left atrium through the pulmonary artery as it is has just come from being oxygenated in the lungs and is now ready to transport that oxygen around the body via the aorta and the arteries for use in respiration.
