Answer to Question 2
Correct Answer: 1
Rationale 1: Lymph vessels drain interstitial fluid, and cancer cells can travel from one area to another via this fluid.
Rationale 2: The tonsils sequester pathogens.
Rationale 3: The thymus gland is the site of T cell maturation.
Rationale 4: The spleen filters blood and can prevent the spread of cancer cells.
Global Rationale: Lymphatic vessels carry more than escaped fluid. Viruses, bacteria, cellular debris, and even cancer cells can enter these vessels. Should these pathogens or cancer cells be permitted to return to the blood stream, an infection (or cancer) could quickly spread throughout the body with potentially disastrous consequences. The tonsils sequester pathogens. The thymus gland is the site of T cell maturation. The spleen filters blood and can prevent the spread of cancer cells.
