The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
A reservoir collects blood drained from the venous circulation. Tubing connects the venous cannulae to the reservoir. Reservoir designs include open or closed systems.
The right side of the heart pumps deoxygenated blood. The right atrium collects venous blood return from the superior and inferior venae cavae and the right ventricle pumps this blood to the lungs.
pulmonary arterial blood as it has moce CO2 than venous
The influx of carbon dioxide in venous blood.
The receiving chambers of the heart are the two chambers on the top, the atria. The right atrium takes venous blood from the body, and the left atrium collects blood coming from the lungs where it has been oxygenated. The serious pumping happens in the ventricles, the two chambers below the atria. The right ventricle pumps the blood to the lungs, and the left ventricle pumps the blood out into the body, both pumping at the same time.
The venous system is responsible for returning deoxygenated blood from the tissues back to the heart. It transports this blood through a network of veins, which have valves to prevent the backflow of blood. The venous system also plays a role in regulating blood volume and pressure in the body.
Blood courses along veins back towards the heart. The veins have one way valves to prevent back flow. Venous blood from below the heart drains into the inferior vena cava. Venous blood from above the heart drains into the superior vena cava. These empty into the right atrium.
