Verified step by step guidance

Understand the primary function of lymphatic vessels: They transport lymph, a fluid containing white blood cells, proteins, and fats, rather than blood.

Recognize the structural similarities between lymphatic vessels and veins: Both have valves to prevent backflow, ensuring unidirectional flow of their respective fluids.

Clarify the connection to the heart: Unlike veins, lymphatic vessels are not directly connected to the heart. They transport lymph to lymph nodes and eventually drain into the venous system near the heart.

Compare the wall thickness: Lymphatic vessels generally have thinner walls compared to veins, as they operate under lower pressure.

Summarize the key differences: Lymphatic vessels transport lymph, have valves, are not directly connected to the heart, and have thinner walls compared to veins.
