Question

If most of the lymphocytes were drained out of an animal via the thoracic duct, the animal would not

• A. Lose it’s ability to combat cancer and produce new lymphocytes
• B. Lose it’s ability to reject skin grafts
• C. Lose its ability to mount a secondary immune response
• D. produce an increased number of red blood corpuscles

Answer 1

The correct option is D

produce an increased number of red blood corpuscles

The number of RBCs produced is not related to the number of WBCs. Hence even if all the lymphocytes are drained out of the body it would not have any bearing on the production of RBCs.
