List out the simllarities between velns and lymph vessels?

Answer»

Lymphatic vessels carry lymph not blood so B and D are incorrect. Both veins and lymphatic vessels are thin walled, carrying blood or lymph at low pressure so their is little elastic tissue needed to respond to changes in pressure as is seen in arteries.

Part of the way blood and lymph move through their respective vessels is by skeletal muscles squeezing the vessels and pushing the fluid through the vessels. The valves prevent the fluid from moving backwards just as squeezing a tube of toothpaste pushes the toothpaste out the open end, not the closed (= valved) end.
