Every organ require oxygenated blood. Most of the blood received by your lungs is deoxygenated.

The nearest organ to the heart that receives oxygenated blood is the lungs. After blood is oxygenated in the lungs, it returns to the heart via the pulmonary veins. From there, the heart pumps this oxygen-rich blood to the rest of the body, including vital organs and tissues.

All of it. Every cell in the human body (exept alveoli cells) require blood that has been oxygenated by the lungs.
The heart is muscular organ which drives oxygenated blood around the whole body.
pulmonary vein carries oxygenated blood to heartAll the vessels that carry blood back to the heart are called veins, all veins carry deoxygenated blood to the heart but pulmonary vein carries oxygenated blood because blood becomes oxygenated in lungsSome veins carry the blood from an organ to the other organ then to the heart. These are called portal veins such as hepatic portal vein and (in reptiles, amphibians and aves) renal portal vein.
The Heart.
The brain and heart require a constant supply of oxygenated blood. The brain is highly sensitive to oxygen deprivation, and even brief interruptions can lead to significant damage. The heart also needs a continuous supply of oxygenated blood to function effectively and maintain its rhythmic contractions. While the lungs and intestines also need blood supply, they do not require it as continuously as the brain and heart.
The organ that pumps blood throughout the body is called the heart. It is a muscular organ located in the chest cavity and is responsible for circulating oxygenated blood to the tissues and returning deoxygenated blood to the lungs for oxygenation. The heart operates through a series of rhythmic contractions, ensuring a continuous flow of blood.
Oxygenated blood is carried by all arteries but one which is the pulmonary artery
