Which of the following statements about the lymphatic system is not correct?
Answer Details
The statement "The lymph vessels are always larger in size than the arteries" is not correct. Arteries are blood vessels that carry oxygenated blood away from the heart to different parts of the body, while lymph vessels are part of the lymphatic system and carry lymph, a fluid that contains immune cells and waste products, from the body tissues back to the bloodstream. Lymph vessels are generally smaller in size than arteries. The other statements are correct. The flow of lymph is assisted by general muscular movement, lymph flows only in one direction due to the presence of valves, lymph is emptied into the blood circulatory system through a vein, and lymph nodes become swollen during serious infections as a result of increased immune activity.
