the red blood cells
In the leopard frog heart, the right atrium carries oxygen poor blood and the left atrium carries oxygen rich blood.
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 vein carries blood with the highest oxygen concentration, as it transports oxygen-rich blood from the lungs to the heart. This freshly oxygenated blood is then pumped out to the rest of the body by the heart.
The pulmonary veins carries oxygen rich blood from the lungs to the heart.
pulmonary artery
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 artery carries blood away from the heart and it is low in oxygen.
The pulmonary vein carries oxygen-rich blood from the lungs to the heart.
Oxygenated blood or oxygen rich blood.
The pulmonary vein and the aorta: a) The pulmonary carries oxygenated blood from the lungs to the heart. b) The aorta carries the oxygenated blood from the heart to the body and head.
