The pulmonary artery
No, deoxygenated from the heart is pumped to the lungs via the pulmonary artery to be oxygenated and returned via The pulmonary veins where it is pumped out the aorta to the body and returned deoxygenated via the vena cava back to the right side of the heart to be pumped out the pulmonary trunk to the pulmonary arteries to the lungs. Some tips, arteries are always away from the heart to must have oxygenated blood in them and the left side leaves to the body so oxygenated blood is pumped there. Hope that helps!
Back to the lungs via veins to be re-oxygenated
Oxygenated blood leaves the lungs and returns to the heart via pulmonary veins to be pumped throughout the body.
Oxygen gets from the lungs to the brain via the bloodstream in around 15-18 seconds. The oxygenated blood leaves the lungs, travels through the pulmonary veins to the left side of the heart, and is then pumped out to the body, including the brain, via the arterial system.
Only when it is the pulmonary vein, as it carries oxygenated blood to the heart. All other veins carry de-oxygenated blood which ends up going to the heart. (The pulmonary vein, however, comes from the lungs, where blood is first oxygenated and then transported to the heart.)
Simply put, the lungs don't get oxygenated blood. The lungs produced oxygenated blood by collected de oxygenated blood and expelling the carbon dioxide (breath out) and refilling with oxygen (breath in). This is a very simple and basic explanation but suffice to say that all this is made possible through tiny blood vessells which can absorb fresh oxygen and expel carbon dioxide via the lungs.
Blood becomes oxygenated in the lungs, then the oxygenated blood goes to the heart via the pulmonary veins and enters the left atrium
The first organ to receive oxygen-rich blood would be the heart. The right ventricle pumps de-oxygenated blood to the lungs. The lungs provide oxygen via interaction with capillaries which in turn sends the oxygen-rich blood back to the left atrium which is found in the heart.
Left atrium via the pulmonary veins from the lungs.
It moves from the lungs back to the heart via the pulmonary veins. Oxygenated blood moves from the heart, through the pulmonary veins into the left atria and then through the bicuspid valve. It then flows into the left ventricle which pumps it through the Aortic semilunar valve and into the Aorta. From there is flows oxygenated blood throughout the whole body and all its tissues.
Oxygen is transported to the blood via the lungs where it diffuses into the bloodstream from the air sacs. Carbon dioxide is transported to the blood as bicarbonate ions or bound to hemoglobin in red blood cells.
Oxygenated blood from the lungs flow back into the heart via the left pulmonary veins into the left atrium, through the bicuspid (mitral) valve, into the left ventricle.
