Yes blood is oxygenated then it is pumped to all parts of the body including the heart.
All blood is red, regardless of where it is in the body. Oxygenated blood and deoxygenated blood have slightly different shades, with deoxygenated blood being darker and oxygenated blood brighter.
Firstly ,Heart pumps deoxygenated coming from body, to the lungs and then the deoxygenated blood turns to oxygenated inside the lungs and after that it comes back to heart . After this, heart again pumps those oxygenated blood coming from lungs, to the body parts .So iIf there would be only one pump system then heart would be as hollow and all the deoxygenated and oxygenated blood would be mixed up inside the heart.
Left side of the heart receives oxygenated blood.
The pulmonary veins carry oxygenated blood to the heart.
Oxygenated
Blood.
The left side of the heart pumps oxygenated blood throughout the body.
Pulmonary vein carries oxygenated blood to the heart from the lungs
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
Arteries always take blood away from the heart. So, arteries that are rich in oxygen always take blood from the heart to the rest of the body. Be careful though. The pulmonary artery is considered an artery because it carries blood away from the heart, but it does not carry oxygenated blood. The pulmonary artery carries deoxygenated blood from the heart to the lungs to become oxygenated. Similarly, most veins carry deoxygenated blood, returning it to the heart, but the pulmonary vein carries oxygenated blood from the lungs to the heart.
Oxygenated blood is pumped out of the heart by the left ventricle.
It's the only vein that carries oxygenated blood. It brings this oxygenated blood back to the heart (into the left atrium) where it can then be pumped around the body.
