The question is this:

12. Regarding the lymphatic system, all of the following are true EXCEPT one. Which one is the EXCEPTION?
  • A. Contains valves which ensures unidirectional lymph flow
  • B. The main white blood cell types in lymph are neutrophils, and macrophages
  • C. Lymph is propelled by contraction of smooth muscle as well as skeletal muscle
  • D. Connects into the blood circulatory system
  • E. Controls interstitial-fluid levels
The answer is B, the explanation is "This is a false statement and therefore the answer choice is correct. The main white blood cell types in the lymphatic system are the lymphocytes; lymphocytes are T cells and B cells." I thought neutrophills are the most abundant white blood cells...

Neutrophils are the most abundant white blood cells, just not in the lymph specifically.
