What lymph vessels closely resemble veins and may be found in the?

Lymph vessels, specifically lymphatic veins, closely resemble veins in structure, featuring similar thin walls and valves that prevent backflow of lymph fluid. These vessels transport lymph, a clear fluid containing immune cells, throughout the body. Lymphatic vessels are found throughout the body, particularly in areas where there are clusters of lymph nodes, such as the neck, armpits, and groin. Their role is crucial for maintaining fluid balance and supporting the immune system.
