Pulmonary oedema
alve
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Are you using this instead of doing homework? Blood comes back into the heart from the lungs via the Pulmonary vein into the Left Atrium.
The blood enters throught the heart throught the right and left atria. As the heart contracts, blood flows into the ventricles and then out from the ventricles.
The vessel that carries blood from the heart to the lungs is called the pulmonary vein. It is one of the few veins that carry oxygenated blood to the heart. The oxygenated blood enters the atrium of the heart.

Blood enters the heart through the Inferior Vena Cava from all the regions of the body below the heart
Circulatory system
Atrium
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Oxygen-poor blood enters the heart through the right atrium
Oxygenated blood enters the left side of the heart (atria) via the pulmonary veins
De-oxygenated blood is dark red. Oxygenated blood is bright red. Both enter the heart- the former enters the right heart; the latter enters the left heart.
Right atrium
The chamber where blood first enters the heart is called the right atrium. It receives deoxygenated blood from the body through the superior and inferior vena cavae. From the right atrium, the blood then flows into the right ventricle, which pumps it to the lungs for oxygenation.
Blood returning from the body systemic circulation first enters which chamber of the heart?
