(6 cards)
1
Q
- recognize foreign antigens and mount humoral (antibodies) and cell mediated antagonistic responses
- Most are nearly round, are slightly larger than RBCs, and have round featureless nuclei and a thin rim of non granular cytoplasm
A
LYMPH
2
Q
are cells with bright orange-red, regular cytoplasmic granules filled with proteins involved in immune system regulation
A
EOS
3
Q
A phagocytic cells whose major purpose is to engulf and destroy microorganisms and foreign material
A
NEUT
4
Q
- are cells with dark purple, irregular cytoplasmic granules that obscure the nucleus
- granules contain histamines and various other proteins

BASO
5
Q
- are less differentiated or less mature neutrophils
- Pink or lavender-staining granules filled with bactericidal secretions

6
Q
- An immature macrophage passing through the blood from its point of origin
- comprise minor component of peripheral blood WBC
- Their tasks are to identify and phagocytose (engulf and consume) foreign particles
- Assist the lymphocytes in mounting an immune response through the assembly and presentation of immunogenic epitopes
- have a slightly larger diameter than other WBCs, blue-gray cytoplasm with fine azure granules, and a nucleus that is usually indented or folded
