Types of Leukocytes Flashcards
1
Q
- 1st Responders to inflammation/infection
- Live in connective tissue 1-4 days
- 2-5 lobed nuclei
- Greatest concentration of leukocytes
A
(Granulocyte)
Neutrophils (aka PMNs or polymorphic nuclei)
2
Q
- Found in underlying epithelial tissue of exposed body areas (ex: GI tract, reap. tract, vagina, etc)
- Seen with helminth infections.
- Can down regulate allergic runs
- Bilobed nuclei
A
(Granulocyte)
Eosinophils
3
Q
- Specific granules release heparin, histamine, et al.
- Can elicit allergic responses
- Mast cells when enter connective tissue
- Irregularly lobed nucleus
A
(Granulocyte)
Basophil
4
Q
- B cells and T cells are this type of leukocyte
- Size depends on activation state
- Nucleus nearly fills cell
A
(Agranulocyte)
Lympocyte
5
Q
- Largest leukocyte
- Become macrophages on entering connective tissue
- Horseshoe, oval, or kidney shaped nuclei
A
(Agranulocyte)
Monocytes
6

- Humoral immunity.
- Precursor to antibody producing plasma cells
A
B cells
7
Q

- Activate B cells
A
T Cells
