Question

Cancer cells in these structures are detected by sentinel biopsies. Trypanosomes (20[1])enlarge the jugulo·digastric type of these structures in Winterbottom’s sign. As centroblasts pass into these structures’ dark zones, cytidine de·aminase rapidly mutates their cell-surface receptors. In TNM staging, cancer cells invade these structures, then metastasize. Fluid enters these structures through an afferent vessel and drains out of a sub·capsular sinus. (*) Germinal centers in these structures and the spleen are the site (10[1])of B cell maturation. The plague causes these organs to form buboes (“byoo-bose”) at the groin or under the armpits. For 10 points, the tonsils are an example of what bean-shaped structures that swell during infection?

ANSWER: lymph nodes [accept germinal centers or GCs; prompt on nodes; prompt on lymphatic tissue or lymphoid tissue or lymphoid organs; reject “lymph” by itself]
