Document Summary
Microbiome contains commensal (harmless) and pathogenic microorganisms. Module 1: infection, immunity, and inflammation (smaller by proportion) Functions of immune system: discrimination and elimination. Antigen: foreign protein that induces an immune response, typically including the production of antibodies (antibody generator) Antibody: protein that is produced in response to, and countering, a specific antigen. Lymphatic system: network of vessels that drains fluid (lymph) that has escaped the blood from the capillaries and entered the surrounding tissues, also called interstitial space. Cells of immune system travel between circulatory and lymphatic systems. Lymphoid organs and tissues act as sites for immune cell generation, training, and/or sites of action. Structure: flexible tissue, divided in two types; yellow and red, filled with hematopoietic cells. Function: red marrow; importance for the immune system, site of hematopoiesis, site of b-cell developmentyellow marrow; some leukocyte development, produces fat and cartilage.
