Document Summary
Leukocyte functions: fight pathogens, microbes : bacteria, fungi (yeasts and molds), viruses, protozoa, algae, innate and adaptive immunity (topic 6, clear debris from damaged areas (review spinal nerve regeneration, a&p i, destroy cancer and virally-infected cells. Leukocytes fight pathogens, clear debris from damaged areas and destroy body cells that have become infected by viruses or become cancerous. The term microbe refers to pathogens (disease causing organisms) that are small and include bacteria, fungi (yeasts and molds), viruses, protozoa and algae. Leukocytes provide both innate and adaptive immunity as will be studied in topic 6. Leukocyte abundance: normal = 4,800-10,800 cells / mm3, measured as part of a cbc w/diff , white blood cell count, number of wbcs in a sample, differential wbc count, relative abundance, count number of each different type in a total of 100 wbcs. Leukocyte abundance is normally measured in the thousands per cubic millimeter (normal range: 4800-10800 cells/mm3; mm3 = microliter or l).
