Blood receives oxygen and releases carbon dioxide as it passes through the lungs (within the blood vessels), therefore it would be oxygenated blood traveling from the lungs into the heart, and through the heart and going out to all major organs, the brain, and to the limbs.
Oxygenated blood flows from the lungs to the heart. Then it gets pumped out to the rest of the body from the left side of the heart.
oxygeneted blood
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
When travelling from legs to heart, blood travels in veins. These veins have a special structure which is adapted for this type of transport. They have valves or pocket-like flaps which prevents blood from flowing backwards or in other words, falling down.
The right side of the heart pumps deoxygenated blood to the lungs, where it picks up oxygen and returns to the left side of the heart.
Blood returning from its cycle through the body is not oxygenated. Once the blood reaches the heart it is then sent to the lungs, where it is oxygenated, then returns to the heart to be sent through the body.
The main vessel that transports blood away from the heart and towards the body is the aorta. The other vessel is the pulmonary trunk. It transports blood away from the heart and towards the lungs.
Pulmonary circulation is the movement of blood from the heart, to the lungs, and back.
Deoxygenated blood goes to the lungs to get rid of carbon dioxide and to pick up oxygen.

Unoxygenated
The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.
The aorta carries blood away from the heart towards the body. The pulmonary artery carries blood away from the heart towards the lungs.
artery carry pure blood but pulmanary artery carry improve blood to lungs from heart
The systemic circulation carries blood between the heart and the rest of the body. In contrast, the pulmonary circulation brings blood between the heart and the lungs.
When travelling from legs to heart, blood travels in veins. These veins have a special structure which is adapted for this type of transport. They have valves or pocket-like flaps which prevents blood from flowing backwards or in other words, falling down.
