Question

Quizplus · Accepted Answer

Lymphatic vessels are most similar in structure to veins. They both have thin walls and valves to prevent backflow of fluid. Arteries have thicker walls and carry oxygenated blood, while capillaries are much smaller and have thin walls for exchange of substances between the blood and tissues. Intestinal villi are finger-like projections in the small intestine that increase surface area for absorption, and nephrons are the functional units of the kidney involved in filtration and urine production, both of which are unrelated to the structure of lymphatic vessels.
