Verified step by step guidance

Understand the function of lymphatic vessels: Lymphatic vessels are part of the lymphatic system, which is responsible for transporting lymph, a fluid containing white blood cells, throughout the body.

Understand the function of veins: Veins are blood vessels that carry deoxygenated blood back to the heart from various parts of the body.

Identify the structural similarity: Both lymphatic vessels and veins have valves. These valves are crucial as they prevent the backflow of fluid, ensuring that lymph in lymphatic vessels and blood in veins move in one direction towards the heart.

Differentiate from other options: Lymphatic vessels do not carry oxygenated blood away from the heart, which is a function of arteries, not veins or lymphatic vessels. They also do not have thick muscular walls like arteries.

Conclude the similarity: The key similarity between lymphatic vessels and veins is the presence of valves that prevent backflow, which is essential for maintaining unidirectional flow of fluid in both systems.
