1

Serum

Plasma minus clotting proteins

2

Hb + CO2

Carbaminohemoglobin

3

Hb + CO

Carboxyhemoglobin

4

Hypertonic solution

Crenation

5

RBC count

5million/ul

6

WBC count

4000-10000/ul

7

Hypotonic solution

Ghosting/lysis

8

Neutrophils granules

Hydrolases, myeloperoxidase, cathepsin g, collagenase, and elastase
Specific-Alk phos, lysozyme, collagenase
Also produce leukotrienes

9

Eosinophils granules

Specific- aryl sulfatase, histaminase, major basic protein and eosinophil cationic protein

10

Basophil granules

Specific- histamine, leukotrienes, SRS, heparin, eosinophil chemotactic factor, neutrophil chemotactic factor

11

Hemopoietic phases

Mesoblastic- 0-3 months
Hepatic- 1-10 months
Splenic- 2.5-6 months
Myeloid- 4 months on

12

CFU-S

GEMM
Granulocytes
Erythrocytes
monocytes
megakaryocytes

13

CFU-L

Lymphocytes

14

RBC development stages

Proerythroblast---Basophilic erythroblast---Polychromatophilic erythroblast---Orthochromatophilic erythroblast----Reticulocyte-----RBC

15

Proerythroblast

1-2 nucleoli, basophilic, undergoes mitosis to make more

16

Basophilic erythroblast

More ribosomes with no nucleoli

17

Polychromatophilic erythroblast

Last stage of mitosis, obvious nuclear/cytoplasm nuclear changes

18

Granulocytopoiesis stages

Myeloblast---promyelocyte---myelocyte----metamyelocyte---band----mature

19

Myeloblast

Unable to tell between lineages, can undergo mitosis

20

Myelocyte

Where you can tell a difference between the lineages and is the last stage to undergo mitosis

21

Neutrophil kinetics

Medullary formation- Any that are developing
Medullary reserve- Ready to enter blood pool
Circulating pool
Marginal pool-Inner vessel walls

22

Metameylocyte

From here on, identify based on nuclear morphology

23

Primary nodule

Only present before birth

24

Secondary nodule

Germinal center present

25

Spleen artery division

Splenic---trabecular---central (white pulp is adventitia)---pulp (no adventitia, has tunica media)---sheathed (single layer ET)---terminal capillaries---splenic sinus---venules---splenic veins

26

Blood thymus barrier

Capillary wall---perivascular space (macrophages here---epithelial reticular layer with tight jx
