left
The right atrium.
the upper and lower part upper part- recives unoxygnated blood and release the oxygenated blood to the whole body system. lower part- or pumping station it recive the unoxygnated blood and the lower part will make it oxygenated blood.
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.
Blood is sucked into your heart then sucked out. It is pumped literaly all over your body. It recives oxygen when going into your lungs and then it takes the oxygenated blood to your heart before pumping that all over your body again. Repeat and repeat.

every body part you have sends blood to your heart

The left atrium receives the blood from the lungs after they have refreshed the oxygen levels.
The left atrium receives the blood from the lungs after they have refreshed the oxygen levels.
