The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.

Right atrium of your heart receives blood from the body.
valves
The four heart valves.
valves prevent the backflow of blood.
Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.
valves help prevent blood from flowing in the wrong direction by opening and closing at the right time to let the heart pump blood effectively.
yes, they get it back by pumping blood to the 4 parts of your heart. when you inhale, it makes rich blood when you exhale it takes out poor blood which turns into carbon dioxide.
The valves of the heart prevent backflow into the arteries. As a result, the heart can efficiently pump the correct amount of blood to the tissues of the body efficiently and rhythmically. -Cheers The valves of the heart prevent backflow into the arteries.

Hollow areas in the heart that receive incoming blood from the lungs and ship it out again are called chambers. The human heart has four chambers.
The heart valves open when blood is flowing through. They close to prevent backflow.
