Document Summary

The lymphatic system ch 24 overview of the lymphatic system. Function of the lymphatic system: transports fluid. Lymphatic organs aid in production & maturation of lymphocytes. Lymphatic system gnerates immune response against antigens. Lymphocytes & macrophages monitor body for foreign substances. Produce antibody proteins that bind to pathogens. Attach to the antigen directly destruction. Come memory cells to quickly attack the antigen if it appears again lymph & lymph vessels. The lymph vessel network transports excess fluid back to the blood. As it flows through the network, lymph is carried through progressively larger diameter vessels: Lymphatic (lymphoid) cells work together to elicit an immune response. 3 types of lymphocytes: t-lymphocytes (t-cells, b-lymphocytes (b-cells, natural killer (nk cells) All 3 migrate through the lymphatic system. T-cells make up about 70-85% of lymphocytes - can recognize a particular antigen on pathogenic cells.
