- Leukocytes= White blood cells (WBC’s)= cells of body’s immune defenses
Non-specific Leukocytes=WBCs of innate immunity= nonspecific cells that help combat foreign invaders
Includes: neutrophils, eosinophils, basophils, monocytes, and natural killers (NK) cells
Specific Leukocytes= WBC of adaptive immunity= specific cells that destroy specific foreign invaders
Includes: T and B lymphocytes
-in this lab we look at blood smears and identify different leukocytes
1. Neutrophils= multilobed nucleus and granules
2. Lymphocytes – specific subtypes cannot be differentiated without special staining
-smallest cells, large nucleus- makes cell look like it is crescent moon
3. Monocytes= largest cells, nucleus is U or kidney bean shape
4. Eosinophils= red granules- 2 lobed nucleus
5. Basophils- purple granule with obscure nucleus
- WBC in body from most to least= Never Let Monkeys Eat Bananas
****KEEP IN MIND- These photos were not taken in class... my photos didn't turn out well. These photos are one's I found on the web. I recommend you check out the photos provided by K. Gard on WebCt... but for general idea, these pictures should help you out : )*****
1. Neutrophils
