Lab Practical 1 Flashcards
granular leukocytes
- neutrophils
- basophils
- eosinophils
agranular leukocytes
- monocytes
- lymphocytes
antigens on O blood group
neither A nor B antigens

A
antigens on AB blood group
A and B antigents
antibodies in plasma of O
anti A and anti B
antibodies in plasma of B

hemoglobinometer
measures that amount of hemoglobin in sample of blood
normal hemoglobin range for females
14.0- 18gHb/100mL
normal hemoglobin range for males
12-16gHb/100mL
hematocrit
measures the percentage of packed red blood cells in a sample
normal hematocrit range for females
37-47%
normal hematocrit range for males
42-52%
formula for calculating hematocrit values
length of packed blood cells in tube (mm) / total length of blood column in tube (mm) x 100= % hematocrit
typical ranges of wbc percentages for normal differential count:
- Neutrophils 40-70%
- Lymphocytes 20-40%
- Monocytes 2-8%
- Eosinophils 1-4%
- Basophils 0-1%
Be able to diagnose the 4 pathologies observed / described in the Differential WBC count activity (HIV / AIDS, acute bacterial infection, parasitic infection / allergy, and mononucleosis).
- HIV / AIDS: low lymphocytes
- acute bacterial infection: high neutrophils
- parasitic infection: high eosinophils
- allergy: high eosinophils
- mononucleosis:

- HIV / AIDS: low lymphocytes
- acute bacterial infection: high neutrophils
- parasitic infection: high eosinophils
- allergy: high eosinophils
- mononucleosis: atypical lymphocytes
S1 heart sound
- first sound; “lubb”
- AV valves close
S2 heart sound
- second sound; “dub”
- closure of semilunar valves
pulse oximeter
and two pulse oximeter types
measures heart rate and blood oxygen saturation (SpO2)
tunica media
-middle layer
tunica externa
-outside layer
tunica interna
-inside layer
inadequate oxygen level of blood
92% or below
