Study Notes
White Blood Cells (WBCs)
- Bacterial infections, appendicitis, and allergy cause an increase in neutrophils
- Parasitic infestation and allergy cause an increase in eosinophils
- Viral infections cause an increase in lymphocytes
- Monocytic leukemia causes an increase in monocytes
Characteristics of WBCs
- Neutrophils: have a 3-5 lobed blue-purple nucleus, small pink cytoplasmic granules, and chromatin threads
- Eosinophils: usually have a blue-violet bilobed nucleus, rarely 3-lobed, red-orange coarse cytoplasmic granules, and chromatin threads
- Basophils: have an irregular shape, may be S-shaped, blue-violet un-segmented bilobed nucleus, rarely 3-lobed, and deep blue or deep purple cytoplasmic granules
- Monocytes: are the largest cells in normal blood, have a kidney-shaped form, large pale blue-violet nucleus, and non-granular cytoplasm
Preparation of Blood Smear and Staining
- Prepare a blood smear and stain it with Leishman stain as described in the previous lecture
Calculations
- Count each WBC seen on the slide and record the number on a differential cell counter until 100 WBCs are counted
- Calculate the percentage of each type of WBC by dividing the number of each type by 100
This quiz is based on the lecture 3 of Practical Physiology, part of Anesthesia Technology course at AL Noor University. It covers the key concepts and topics discussed in the lecture.
