Card Set Information
1. Most Abundant.
2. 55-75% (3,000-7,500/mm3)
3. Stain poorly
4. short live cells. few hours to few days of life, but produced 80,000,000new cells /minnute by bone marrow
1) 1-4% of WBC (50-400/mm
2) Phagosites, but kill microbes extracellularly
3) Granules, stain red with acidic dye eosin (dye used to stain leukocytes)
4) Nuclue appears lobed
5) Granules contain distructive enzymes for killing bacteria
5) Leukotrienes, prostaglandins, chemicals that promotes inflammation
6) Live 8-12 days
1) make up 0-1% of WBC (25-100/mm3 of blood)
2) Granules stain dark purplish blue (baso) w/ basic dye methylene blue
3) Have a lobed nucleus
4) Release histamine, leukotrienes, and prostaglandins
5) Live few hours to few days
Have compact nuclei and have no visible cytoplasmic granules.
1) Make up 2-8% WBC (100-500/mm3 blood)
2) Are important in phagocytosis and serve as antigen-presenting cells in the adaptive immune responses
3) Differentiate into macrophages and dendritic cells when they leave the blood and enter the tissue
4) Long lived (for months) and multiply
1) 25-40% of the WBCs (1,500-4,500 of blood).
2. mediate the adaptive immune responses.
3.circulate back and forth between the blood and the lymphoid system of the body
nThey have a life span of days to years.
ne. There are 3 major populations of lymphocytes
: B-Lymphocytes, T-Lymphocytes, NK cells
