the left atrium is above the left ventricle. the blood which has been oxygenated from the lungs due to the gas exchange between the alveoli and capillaries comes here from the pulmonary artery this blood then gets sent to the left ventricle through the bicuspid valve this stops the backflow of blood but it allows the blood to go to the left ventricle but does not allow the blood to go back

Incompetent mitral valve allows the retrograde flow of blood from the left ventricle into this structure?

What is the structure of the pulmonary vein?
The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart
Where does the left atrium lead to?
The left atrium empties into the left ventricle. The left atrium and left ventricle are separated by the left AV valve, or mitral valve.
What are the 4 chambers of the heart?
Right Atrium , Left Atrium , Right Ventricle , Left Ventricle
Where is the blood that enters the left ventricle coming from?

What chamber of the heart do the pulmonary veins enter?
the left atrium...it pumps blood thereThe pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.
The upper chambers of the heart are?
The two upper chambers are called the atria. A single atria is an atrium.
What are the four chambers of the heart are called?

What is the placental mammal's structure of the heart?
All mammals (monotremes, marsupials, and placental mammals) have the same heart structure: a four chambered heart. The four chambers are the left atrium, the left ventricle, the right atrium, and the right ventricle. The right atrium receives deoxygenated blood from the veins. It pumps it into the right ventricle. The right ventricle pumps it into the pulmonary arteries, which go to the lungs. The lungs have received oxygen and give it to the blood coming through. The now oxygenated blood flows back to the heart by pulmonary veins, and is received by the left atrium. The left atrium pumps the oxygenated blood into the left ventricle. The left ventricle pumps the blood to all of the body through arteries.
What does the left atrium carry?
The left atrium carries oxygenated blood.
Does the atrium have depxgyenated blood?
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.
