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.

The two lower parts of the heart that pump blood out to the body are called the ventricles. The right ventricle pumps deoxygenated blood to the lungs for oxygenation, while the left ventricle pumps oxygenated blood to the rest of the body. Together, they play a crucial role in the circulatory system by ensuring efficient blood flow.

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 vein that collects deoxygenated blood from the posterior parts of the body and returns it to the heart is the inferior vena cava. It gathers blood from the lower regions, including the legs, abdomen, and pelvis, and transports it to the right atrium of the heart. The superior vena cava serves a similar function for the upper parts of the body. Together, they ensure that blood circulates back to the heart for reoxygenation.
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
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 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.
