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.

Neutrophils are the most abundant in the blood, but not the lymph.
