Detailed explanation-1: -Lymph vessels are thin walled tubes that, similar to blood vessels, carry white blood cells, fluids and waste. Unlike veins and arteries, however, lymph vessels do not carry red blood cells and their main function is to remove excess fluid from tissues.
Detailed explanation-2: -Larger lymphatic vessels are similar to veins in terms of their three-tunic structure and the presence of one-way valves to prevent backflow. These one-way valves are located fairly close to one another, and each one causes a bulge in the lymphatic vessel, giving the vessels a beaded appearance (see Figure 19.3.
Detailed explanation-3: -Like veins, the lymphatic tributaries have thin walls and have valves to prevent backflow of blood. There is no pump in the lymphatic system like the heart in the cardiovascular system.
