Use the infоrmаtiоn in the fоllowing cаse study to аnswer this question and the ones after it. A 27-year-old lacrosse player visits her doctor complaining of lethargy. She also indicates that she has been waking up with night sweats and random fevers lately. Upon further discussion she indicates that she has recently experienced weight loss and widespread lower back pain but chalked it up to training and lifting for the upcoming season. The doctor examines her and discovers that she has swollen lymph nodes in her neck and arm pits, but they are not causing her any pain. He orders a needle biopsy of the swollen nodes, a complete blood count (CBC), and chest and abdominal X-rays. The results of the CBC indicated elevated levels of eosinophils and lymphocytes. The X-rays demonstrated the presence of more swollen lymph nodes in the chest, pleural effusion (fluid around the lungs), and splenomegaly (swollen spleen). The biopsy results confirmed the presence of Reed-Sternberg cells. The doctor diagnosed the woman with Hodgkin’s lymphoma and referred her to an oncologist to determine a treatment plan. Hodgkin’s lymphoma is a form of cancer that is characterized by abnormally dividing and abundant lymphoid cells outside of the bone marrow. What are the functions of the lymph nodes? Which cells are normally found in lymph nodes and which specific ones could be affected by lymphoma?
