Yes it is a Blood Vessel
The vena cava carries deoxygenated blood into the left atrium.
The Pulmonary Vein carries oxygenated blood from the lungs to the Left Atrium.
pulmonary veins
Blood that comes in to the right atrium comes from the pulmonary vein.
The pulmonary veins bring oxygenated blood from the lungs to the left atrium of the heart.
vena cava
The blood enters through the superior and inferior vena cava.
The superior vena cava conducts blood from the head to the right atrium.
the left atrium...it pumps blood thereThe pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.
The left atrium of the heart receives oxygented blood from the pulmonary veins returning oxygenated blood to the heart.
The left ventricle is the heart chamber that most directly pumps blood to the vessel network. It pumps oxygenated blood out into the body through the aorta, which then branches out into smaller arteries to deliver blood to the rest of the body.
well you have two atria the right atrium and left atrium but i think the right atrium has deoxygenated blood and the left atrium has oxygenated blood.
