The pulmonary artery (which takes blood from the hear to the lungs to be recharged with oxygen).
If it's carrying oxygen-poor blood, it must be going to the lungs, so I would guess you would call that the pulmonary artery.
the artieries that lead to your heart have carbon dioxide (Co2) in them and the arteries that lead to your body are carrying oxygen to the body parts
poor
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
Oxygen-poor blood
The pulmanary artery carries oxygen poor blood.
The aorta carries oxygen-rich blood from the heart to all parts of the body except to the lungs. Oxygen-poor blood is carried to the lungs from the heart through the pulmonary artery.
The chamber is the Right Atrium which receives oxygen poor blood from the body through both the inferior and superior vena cavas to send it to the lungs through the pulmonary artery so that it be oxygenated. Hope this helps!
pulmonary artery
In the circulatory system, deoxygenated blood is found on the right side of the heart, in the pulmonary artery, and in the systemic veins. The pulmonary artery brings low-oxygen blood to the lungs. The systemic vein carry deoxygenated blood from the body tissues to the right atrium.
I'm pretty sure that the frogs pulmonary artery carries oxygen poor blood to the lungs.
The pulmonary artery carries oxygen-poor blood. The pulmonary vein carries oxygen-rich blood.
