Oxygenated blood is pumped out of the heart by the left ventricle.
Through the inferior and superior vena cavaThe left atria of the heart is where oxygenated blood enters, it is then pumped to the left ventricle and then to the rest of the body thru the systematic circuit. The heart is separated by the septum, which separates oxygenated and deoxygenated blood.
Through both! The pulmonary veins carry oxygenated blood to the heart and then arteries carry it from the heart to the body as a whole. Veins return de-oxygenated blood to the heart.
oxygenated
The heart takes in oxygen from the environment and delivers it to cells.
A four chambered heart is a closed system and ensures that all blood passing through it is oxygenated. A three chambered heart has both oxygenated an non-oxygenated blood mixed in the single ventricle therefore the blood is only half oxygenated. A three chambered creature would suffer from exhaustion long before a four chambered creature.

Heart.
The blood flowing through the veins carry the carbon dioxide from the cells of all parts of the body to the heart. Hence we say that the veins transmit the De-oxygenated blood from all parts of the body to the heart. The De-oxygenated blood collected in the heart flows to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs. Then the oxygenated blood flows to the heart through the pulmonary vein. Then the oxygenated blood flows to all parts of the body through the arteries. So blood flows into the heart through the veins, and flows out of the heart through the arteries. Normally the De-oxygenated blood flows through the veins and the oxygenated blood flows through the artery. The only exceptions are the pulmonary artery that transmits de-oxygenated blood from heart to the lungs and the pulmonary vein that transmits oxygenated blood from lungs to heart. This is because blood flows into the heart by veins and flows out of the heart by arteries.
Blood flows through veins to get to the heart. Arteries are blood vessels for the blood to leave the heart once it has been oxygenated.
Oxygenated blood gets to the hearts muscles through three coronary arteries that are outside the heart. They branch from the aorta just above the left ventricle and conduct blood through smaller arteries and capillaries into the walls of the heart. Veins passing through the heart join to form the coronary sinus, a cavity from which venous blood flows into the right atrium.
Through both! The pulmonary veins carry oxygenated blood to the heart and then arteries carry it from the heart to the body as a whole. Veins return de-oxygenated blood to the heart.
Oxygenated blood.

The heart takes in oxygen from the environment and delivers it to cells.
Blood is de-oxygenated when it it pumped into the lungs, and after going through the lungs, is now oxygenated.
