Valves
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.

There are two ways that blood is kept flowing in the same direction. The heart is pumping it in that direction, and blood vessels contain valves which prevent blood from flowing in the wrong direction.
The veins carries blood from the body to the heart.
Veins. Veins carry unoxygenated blood towards the heart.
Yes, heart valves control the direction of blood flow by opening and closing to ensure that blood flows in one direction through the heart. This helps to maintain the efficiency of the heart's pumping action and prevent backflow of blood.
Valves and blood vessels control the flow of blood through the heart. The aorta governs the functioning of these structures by being the main artery in the cardiac system.
Arteries
Left side
The structures of the circulatory system include the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels to deliver oxygen and nutrients to cells and remove waste products. The blood vessels transport the blood to and from the heart, while capillaries allow for the exchange of substances between the blood and tissues.
