Difference between Vein and Artery:
Vein and artery are two types of blood vessels that play an important role in the circulation of blood in the body. Although both of them have similar functions, there are some key differences between them. One of the main differences between veins and arteries is the presence of valves.
Presence of Valves in Veins:
Veins are blood vessels that carry blood from the body back to the heart. They have thin walls and are located closer to the surface of the skin. One of the main features of veins is the presence of valves. These valves are one-way flaps that prevent the backflow of blood. They work by opening and closing as the blood flows through them. This helps to maintain the flow of blood towards the heart and prevents the blood from flowing back into the veins.
Absence of Valves in Arteries:
Arteries are blood vessels that carry blood away from the heart to the rest of the body. They have thick walls and are located deeper in the body. Unlike veins, arteries do not have valves. This is because the flow of blood in the arteries is maintained by the pumping action of the heart. The blood flows in one direction only, from the heart to the rest of the body.
Conclusion:
Therefore, the correct answer is option 'A' which states that veins differ from arteries in having valves to control the flow of blood.
