to keep the right lung company
It conveys oxygenated blood from the lungs into left atrium of the heart.
The job of the pulmonary vein is to carry blood from the lungs to the heart. It brings oxygen-rich blood to the left atrium.
Your left ventricle pumps oxygen rich blood throughout the body while the left atrium receives the oxygen rich blood from the lungs.
Its around 30% left in the lungs
The air left in your lungs after exhaling is called "Expiratory Reserve".
The left atrium receives blood from the lungs
Lungs~pulmonary veins~left atrium~left ventricle
Our lungs help us breath and they let us live.
The pulmonary veins deliver blood to the left atrium from the lungs.
The right and left ventricle almost have the same job. The left ventricle has a harder job then the right ventricle. The right ventricle only has to contract and blood is forced out of the heart through a large vessel. And then has to pump the blood into the lungs. The left ventricle has a lot harder job it actually works six times more harder then the right ventricle. The left ventricle has to pump blood through your WHOLE body. Yea it has a lot harder job. :)
The deoxygenated blood goes into the lungs through pulmonary artery from the right ventricle. the oxygenated blood again enters the heart from the lungs by pulmonary veins to the left atrium.
the person who left the job :)
