Document Summary
*iclicker* an example of your inate immune structure or function would be. First line of defense such as your integument (skin) Macrophages recognizing antigens without extra activation then phagosityzing those antigens. Picks up thoruhg capilaries and ends up in the blood, back towards he heart. Tonsils: multiple aggrigations of large lymphatic nodules embedded in a mucus membrane. Enlarged tonsils and/or infections of them may lead to their removal. Macropahages ingest bacteria, old and damages red blood cells, and platelets. Abdominal trauma can result in a ruptured spleen. Total or partial removal can leed to reduced immune capacity. Thymus gland: functions in immunity by maturing and distributing t lymphocites (tcells) distributing t lymphocites (tcells) Thymus reduces in size and function as the immune system amatures throughout childhood. Lymmphatic capillaries-> lymph vessels/nodes-> thoratic duct-> drain into the subclavian vein back to the heart. Lymphatic vessels are similar to your veins with the semi-lunar back-flow valves.
