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 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!
The major artery that carries oxygen-rich blood is the aorta, which delivers blood from the heart to the rest of the body. The major vein that carries oxygen-poor blood is the superior vena cava, which returns blood from the upper body to the heart.
pulmonary artery
Oxygen-poor blood leaves the heart via the pulmonary artery and is transported to the lungs for oxygenation. Once it picks up oxygen in the lungs, it returns to the heart through the pulmonary vein to be pumped out to the rest of the body.
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.
