Blood is:55% Plasma45% CellsWhat is plasma?
Plasma is theliquid portionof blood
Plasma is:
91.5% water. Transport medium.
7% proteins, e.g., clotting factors, antibodies
1.5% other solutes, e.g., hormones,vitamins, amino
acids, glucose, fatty acids, nitrogen wastes,
electrolytes (Ca++, Na+, K+, H+)
What kinds ofcells do we findin the blood?
Red Blood Cells (RBCs) = Erythrocytes
• >99% of total blood cells are RBCs
• ~5 million/ml
• Hb• Fe
• Transport O2 and CO2
• No nucleus when mature
Platelets = Thrombocytes
• Involved in blood clotting
• 150,000 – 400,000/ml
White Blood Cells (WBCs) = Leukocytes
Defense system
5,000 – 10,000/ml
There are 5 different types of WBCs
Neutrophils = PMNs = Polymorphonucleocytesor Poly’s
• Most abundant ofthe WBCs
• Phagocytic
• Kill bacteria
Basophils
• Release histamine.
• Their numbers increasein allergic reactions
Eosinophils
• Fight parasitic infections
• Some allergic reactions,esp. asthma, are theresult of the malfunction-ing of eosinophils.
Lymphocytes
• Produce antibodies
• Fight viruses
What % of blood is plasma?
A.) 65
B.) 45
C.) 55
D.) 90
Monocytes
• Size-wise, is largestof the WBCs• Phagocytic
• Large kidney-shapednucleus
The blood cell that releases histamine in an allergic reaction is
A.) neutrophil
B.) basophil
C.) esinophil
D.) lymphycyte
Important Hematology Lab Terms
1. CBC = Complete Blood Count
Normal (nl) values:RBCs: 4.2-5.9 million/mlWBCs: 5,000-10,000/mlPlatelets: 100,000 – 400,000/ml
CBC c diff (differential)
Nl values:PMNs: 60-70%Lymphos: 20-25%Monos: 3-8%Eos: 2-4%Basos: 0.5-1%
Hematocrit (or ‘crit, if you want to sound cool)
The percent of whole blood made up of redblood cells.
Nl value: 40-50%
