PATHOLOGY

Detailed explanation-1: -Veins have valves to prevent this backflow of blood. Valves ensure that blood flows only in one direction through veins. Therefore, veins have valves, not the arteries.

Detailed explanation-2: -Veins: Unlike arteries, veins don’t have to carry highly pressurized blood, but they do have to carry large volumes of deoxygenated blood back to your heart. Thin, less elastic walls help them handle high volumes and low pressure. Most veins have valves that open and close.

Detailed explanation-3: -The valves are present in the veins, known as the bicuspid valves which are characterized by a pair of flap-like structures. This structure helps in regulating the flow of blood. The pair of flaps consists of tissues which are elastic in nature.
