blood Flashcards
1
Q
function
A
transport (gases, nutrients, cells, leukocytes)
homeostasis (temp., fluid content, pH, salt)
wound healing (clot formation)
2
Q
composition of blood
A
fluid = plasma
formed elemtns = cells
3
Q
plasma exchanged
A
- aqueous solution
- exchange interstitial fluid into intracellular flluid
- proteins (osmotic gradient)
- transport (albumin and globulins
- clotting (fibrinogen)
4
Q
blood cell structure
A
almost all are fully formed elements
5
Q
erythrocyte
A
transport of gasses (o2 to mass it)
no regreation regoil
6
Q
leukocyte perks
A
immune respond = transparent collected
7
Q
granulocyte
A
secretory granules visible multilobed nucleus originate in bone marrow PMNs myeloid cells type of leukocyte
8
Q
agranulocytes
A
secretory granules not visible
9
Q
neutrophils
A
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
Q
eoisinophils
A
1-5% bilobed nucleus short life span phaocytic granules usually red, same size "bag of marbles
11
Q
basophils
A
<1% bilobed nucleus (hard to see) phagocytic granules are blue metachromasia, sometimes red granules proteoglycans histamines
12
Q
lymphocytes
A
20-50%
nucleus = most of cell, blue cytoplasm
13
Q
monocytes
A
3-8%
largest circulating centre
nucleus - bean shaped
cytoplasm - blue/grey
14
Q
platelets
A
small cells
fragments of megakaryocyte
contains all organelles except nucleus
first line in clotting (bind collagen, scaffold, allow thrombin)
