Final Exam: Lab 9 Blood Tests Flashcards
What is the function of blood plasma?
a. Regulation: hormones and temperature
b. Protection: cells of immune system
c. Transportation: carries through body respiratory gases, nutrients, and waste
Flow diagram of negative feedback system that maintains a normal number of red blood cell
decrease O2 -> cause release of erethropoetein from kidney -> formation/creation of RBC
RBC tests
Hematocrit
Total RBC Count
Hemoglobin concentration
Hematocrit
- packed cell volume
- percentage of blood volume comprised of cells
- Female: 36 - 46%
- Male 41-53%
Total Red Blood Cell Count
- the total number of RBCs in 1 mm3 of blood
- 4.5 - 5.9 million rbc/mm3
- carry o2
Hemoglobin concentration
- concentration of hemoglobin in g/dl
- F: 12-16 g/dl
- M: 13.5 - 17.5 g/dl
White blood cell tests
total white blood cell count
differential whtie blood cell count
total white blood cell ount
- total number of WBCs in a mm3 of blood
- normal range: 4000 - 11,000 wbc/mm3
- can diagnose leukocytosis and leukopenia
leukocytosis
- increased number of white blood cells.
- causes infection, some types of poisoning
- increase eosonophils
leukopenia
- decreased number of white blood cells
- causes infection that damage wbcs (for example, measles), cirrohosis of liver, radiation exposure
differential white blood cell count
percentage of each of the 5 types of white blood cells
- neutrophils - bacteria
- eosinophil - phagocite
- basophils - anticoagulant
- monocyte - phagocyte
total platelet count
- total number of platelets per mm3 of blood
- normal range: 130,000 - 400,000 platelets/mm3
blood types
Type B blood type has antigen B with antibody A. it cannot receive Blood type A or AB because It will agglutinate type A antigen.
