Veins have valves which allows blood to flow in only one direction.Arteries do not have valves yet the blood flows in only one direction .can you explain why
Answers
Answer:
Arteries have thick walls and they receive blood at very high pressure from the left ventricle. Due to this high pressure and the elasticity of the vessels, the blood flows only in one direction.
Explanation:
Veins are the blood vessels that return deoxygenated blood from the organs back to the heart. Deoxygenated blood that flows into the veins is collected in the tiny blood vessels called capillaries.
Arteries carry oxygenated blood along with nutrients from the heart to the other parts of the body. They began with the aorta, the large artery leaving the heart. They branch several times, becoming smaller as they carry blood further.
The heart has four valves that allow blood to flow through the heart only in one direction. The mitral valve and the tricuspid valve are between the atria and ventricles. As the heart pumps the blood, the valves open and close tightly. These valves make sure that blood flows only in one direction preventing the backflow.
Hence, the blood in the arteries flows only in one direction even though they do not have valves.
