White Blood Cells (Leukocytes) Flashcards
White blood cells (WBCs) are also called
leukocytes
leukocytes are
immune system cells
how many types of leukocytes are there typically
5
difference between leukocytes and red blood cells (RBCs)
leukocytes have nuclei RBCs do not
leukocyte nuclei have
extensions called lobes
what distinguishes different types of WBCs
shape of the nucleus number of lobes appearance and color of granules
Cell organelles form
granules
what is more easily seen in some types of leukocytes
granules
criteria to distinguish and quantify WBCs in the lab
Wright Stain Leukocytes in blood Measurements of leukocytes
Wright Stain
combined from Methylene Blue and Eosin used to treat prepared slides of blood some WBCs are named based on their affinity to its components
Leukocytes are nearly colorless. True or False
colorless
Methylene Blue, acid or base
alkaline (basic)
Eosin, acid or base
acidic red
What two groups are leukocytes are separated into?
Agranulocytes- generally hard to see granules
Granulocytes- easily seen granules
Agranulocytes
typically hard to see granules
lymphocytes monocytes
lymphocytes
smallest of WBCs can not see granules nuclei are spherical and fill them difficult to see a thin rim of cytoplasm
