Lab 1 Flashcards
(19 cards)
Serum
Plasma without clotting proteins
Constituents of plasma
90% water, electrolytes, nutrients, plasma proteins and waste
Used coagulants (proteins) in the blood plasma itself
The intrinsic system of coagulation
Uses coagulants plus factors from damaged tissue. Faster than intrinsic.
Extrinsic system of coagulation
Red blood cells
99% Formed elements
4-6 Million per mm3
Pale center
Oxyhemoglobin vs Carbaminohemoglobin
Full of oxygen vs full of carbon dioxide
Hematocrit
Separating formed elements from plasma. Measures percentage of RBCs in blood. 40-54% males and 38-46% in women.
Anemia and types
Low oxygen carrying capacity
Reduced number of RBCs
Reduced amount of hemoglobin
Abnormal RBCs or hemoglobin
Polycythemia
Increased number of RBCs
Leukocytes
4-11000 per mm3
Fighting of infection
Made of granulocytes and agranulocytes
Neutrophils
40-70% WBC
Slightly visible granule in cytoplasm
Phagocytize bacteria
Eosinophils
1-4% WBCs
Reddish/Orange granules in cytoplasm
Attack parasitic worms and activate allergic reactions
Basophils
<1% Of WBCs
Purple/black granules
Release histamine (inflammatory response)
Lymphocytes
20-45% WBCs
Smallest with no granule, large nuclei
Immune response
Monocytes
4-8% WBCs (largest)
No visible granules and pale kidney shaped nuclei
Clean up left over garbage (macrophages)
Leukopenia
Reduction in the number of WBCs
Leukocytosis
Increase in the number of WBCs
Leukemia
Increase in number of WBCs with an abnormal ratio of the different kinds, or abnormal looking WBCs
Platelets
150-400,000 per mm3
Pieces of cells from megakaryocytes
Function to plug broken blood vessel walls causing hemostasis
