Flashcards in blood Deck (14):
1

function

transport (gases, nutrients, cells, leukocytes)
homeostasis (temp., fluid content, pH, salt)
wound healing (clot formation)

2

composition of blood

fluid = plasma
formed elemtns = cells

3

plasma exchanged

-aqueous solution
- exchange interstitial fluid into intracellular flluid
-proteins (osmotic gradient)
-transport (albumin and globulins
-clotting (fibrinogen)

4

blood cell structure

almost all are fully formed elements

5

erythrocyte

transport of gasses (o2 to mass it)
no regreation regoil

6

leukocyte perks

immune respond = transparent collected

7

granulocyte

secretory granules visible
multilobed nucleus
originate in bone marrow
PMNs
myeloid cells
type of leukocyte

8

agranulocytes

secretory granules not visible

9

neutrophils

40-70% - majority of leukocytes
multi-lobed
chemotactic to inflammation site
phagocytic (releases pus)
granules don't stain well
1o granules - lysosomes
2o - inflammaion
3o = cams

10

eoisinophils

1-5%
bilobed nucleus
short life span
phaocytic
granules usually red, same size
"bag of marbles

11

basophils

<1%
bilobed nucleus (hard to see)
phagocytic
granules are blue
metachromasia, sometimes red
granules proteoglycans
histamines

12

lymphocytes

20-50%
nucleus = most of cell, blue cytoplasm

13

monocytes

3-8%
largest circulating centre
nucleus - bean shaped
cytoplasm - blue/grey

14

platelets

small cells
fragments of megakaryocyte
contains all organelles except nucleus
first line in clotting (bind collagen, scaffold, allow thrombin)
