Document Summary
In order to survive, animals developed mechanisms to compete against microorganisms and limit damage caused by them. Structural basis of the immune system interlinks with blood circulation comprises: Functions: captures lost fluid from the blood - filtration and reabsorption in capillaries is not equal! You can"t see lymph veins, you can"t feel blood flow (like pulse) - occasionally you"ll get swollen glands. Lymphatic system = one way system - has valves. Flows through ever-larger vessels: collecting vessels, trunks and ducts, empty into venous system, right lymphatic duct and thoracic duct. Larger thoracic duct empties into left subclavian vein. Divisions of the immune system: our immune system can be divided into 2 distinct but 0ver-lapping categories. Innate or non-specific immune system: adaptive or specific immune system - if infection overwhelms innate system adaptive/specific immune system kicks in and activates aggressive immune response.
