The heart valves open when blood is flowing through. They close to prevent backflow.
Heart valves control the flow of blood into, out of, and within the chambers of the heart. The main function is to let blood flow in one direction only, ensuring that blood does not flow backwards.

The valves of the heart open when blood is flowing through, allowing it to move from one chamber to another. The atrioventricular valves open to allow blood to flow from the atria to the ventricles, and the semilunar valves open to allow blood to flow out of the heart into the arteries.
The aortic valve opens during systole to allow blood to be pumped from the left ventricle into the aorta. This process is part of the cardiac cycle that ensures blood is effectively circulated throughout the body.

A crayfish heart is a simple tubular structure that pumps blood throughout its body. It consists of ostia, openings that allow blood to enter the heart, and muscular chambers that contract to push blood out. The heart is part of a system of open circulation, where blood flows freely in the body cavity without being enclosed in vessels.
The ARTERIES carries the blood away from the heart.
The valves in the heart act as one-way switches that allow blood to only flow one way. So every time the contracts, the blood flows out and into the lungs or the body, depending on which side the blood is circulating through.
veins, but technically, they are not part of the heart.
The systemic circulation is the part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart. In contrast, the pulmonary circulation is the part of the circulatory system that carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart.
