inguinal lymph nodes
lymph nodes located in the inguinal (groin) area of the lower abdomen
is produced by the t cells, is a family of proteins released by cells when invaded by a virus; causes noninfected cells to form an antiviral protein that slows or stops viral multiplication

a benign abnormal collection of lymphatic vessels forming a mass
an abnormal accumulation of fluid primarily in the legs and ankles that occurs when veins or lymph vessels do not drain properly
are WBC's that specialize so they can attack specific microorganims; formed in bone marrow and undergo further maturation and differentiation in lymphatic tissue throughout the body including lymph nodes, spleen, thymus, tonsils, and peyer's patches; two major classes are b cells, and t cells
are produced by the t cells, direct the immune response by signaling between the cells of the immune system; attract macrophages to the infected site and prepare them to attack
a general term applied to malignancies that develop in the lymphatic system
a type of phagocyte, protects the body by ingesting (eating) invading cells by interacting with the other cells of the immune system

western blot test
detects the prescense of specific viral proteins, produces more accurate results
