Arteries always carry blood from the heart. In this case, the artery is the aorta.
Veins and arteries are not classified by whether they carry oxygen-rich or oxygen-poor blood. They are classified according to whether they carry blood to the heart or away from the heart. Veins carry blood to the heart and arteries carry blood away from the heart. So the pulmonary vein carries blood to the heart, which is why it is a vein. Also, the pulmonary artery, which carries oxygen-poor blood to the lungs is an artery because it carries blood away from the heart.

artery
Systemic veins, not to be confused with pulmonary veins, carry oxygen poor blood back to the heart.
oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.

It carries blood toward the heart.
Its carries "oxygen rich blood" away from the heart.
In the leopard frog heart, the right atrium carries oxygen poor blood and the left atrium carries oxygen rich blood.
the red blood cells
Well, blood is not carried. Blood, or blood cells, carry oxygen to and from the heart, spreading it throughout the body. Blood basically carries oxygen, and it itself is not carried.
The pulmonary veins carries oxygen rich blood from the lungs to the heart.
pulmonary artery
The pulmonary artery carries blood away from the heart and it is low in oxygen.
The pulmonary artery carries blood from the heart to the lungs. Unlike the blood in other arteries, the blood of the pulmonary artery is oxygen-poor.
The pulmonary vein carries oxygen-rich blood from the lungs to the heart.
