Your heart pumps blood to all parts of the body.
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.

A redout occurs when the body experiences a negative g-force that causes a blood flow from the lower parts of the body to the head. It is the opposite effect of a greyout.
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.

Through the right ventricle =D
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.

The blood vessel that takes blood to the digestive organs and lower body is the abdominal aorta. It branches into several arteries, including the mesenteric arteries, which supply the intestines, and the common iliac arteries, which supply the lower body. This system ensures that the lower parts of the body and digestive organs receive the necessary oxygenated blood for their functions.
Upper parts will turn plae due to lack of blood, lower parts will turn dark blue or purple as the blood pools inside the body, this is called levidity.
G-forces can make you blackout by causing a sudden decrease in blood flow to the brain. This occurs when the forces push blood away from the brain towards the lower parts of the body, leading to a lack of oxygen and nutrients reaching the brain, resulting in a temporary loss of consciousness.
