Blood is pumped around the circulatory system by the heart.
The right ventricle
The arteries carrying blood to the lungs contain deoxygenated blood. In contrast, other arteries carry oxygen-rich blood.
Deoxygenated. The blood is carried by the pulmonary arteries from the heart to the lungs to replenish the oxygen.

Blood enters the lungs through the pulmonary arteries.
The pulmonary arteries carry blood to the lungs to be oxygenated.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
The right ventricle pumps O2 poor blood into the lungs. The ventricular pressure has to be greater than that of the pulmonary artery to open the pulmonary valve and push the blood to the lungs.
The pulmonary arteries carry deoxygenated blood to the lungs.

Pulmonary Arteries
The bronchial arteries supply oxygenated blood to the lungs. The bronchial arteries branch off of the aorta, which is the main artery in the body.
