Through the right ventricle =D
The atria Actually, it is the contractions (squeezing) of the ventricles (the lower parts of the heart), not the atria (the upper parts), that do the pumping. That's why the lower part of the heart is larger, and the muscular walls are thicker. The atria receive the blood from the body and pump it down into the ventricles.
The aorta carries oxygen-rich blood from the heart to all parts of the body except to the lungs. Oxygen-poor blood is carried to the lungs from the heart through the pulmonary artery.
when blood enters the heart its a bright cherry red colour when it leaves its a dull red/ brown colour hope this helps :) x
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
left part of heart
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
Your heart pumps blood to all parts of the body.

There are three blood vessels that carry blood to the heart in deoxygenated form. Superior vena cava that carries blood from upper parts of the body like brain etc. Then there is inferior vena cava that carries blood from lower body parts like legs etc. Last is pulmonary vein that brings oxygenated blood from lungs to the heart.
The aorta carries oxygen-rich blood from the heart to all parts of the body except to the lungs. Oxygen-poor blood is carried to the lungs from the heart through the pulmonary artery.
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
The blood in veins is at a lower pressure than it is in the arteries. The lower pressure makes for challenges getting that blood back to the heart. As there is less force (pressure) in the veins, blood would pool in the lower parts of the body if there were not mechanisms to prevent that. There are three different things that help blood get back to the heart. The three mechanisms are: venous valves, muscular pumps, and the respiratory pump.
The vena cava (both) are very large veins. All veins carry blood back to the heart. In the case of the vena cava, this is blood from the upper body (superior vena cava) and from the lower body (inferior vena cava).
The heart pumps all of the blood away from and back into the body. The parts of the heart that pump oxygenated blood back to the body are the left atrium, which pumps blood into the left ventricle, and the left ventricle, which pumps the blood back into the body. The blood exits through the heart through the aorta.
