Two of the body's most important function
|
Transportation & Protection
|
|
|
Systems that provide transportation and protections
|
Circulatory & Lymphatic system
|
|
|
What is blood
|
Viscous, red fluid that contains red blood cells, white blood cells, and platelets suspended in a light yellow fluid called plasma.
|
|
|
Composition of Plasma
|
55% of the bloods volume. Remaining 45% is composed of blood cells and platelets
|
|
|
Blood PH range
|
7.35 to 7.45
|
|
|
Average adult blood volume
|
5 to 6
|
5 to 6 L
|
|
Critical functions of blood
|
1) transports oxygen and nutrition to cells and waste products away from the cell, and transport hormornes from endocrine glands to tissues and glands
2) regulate acid-base balance (pH) 3) protects body against infection with special cells and prevent blood loss with special clotting mechanisms |
|
|
What gives blood there rich color
|
Erythrocytes (RBCs)
|
|
|
A mature RBC contains
|
Cytoplasm and red pigment hemoglobin
|
|
|
Hemoglobin content is expressed as
|
Normochromic or hypochromix anemia
|
|
|
RBC size is expressed as
|
Macrocytic, microcytic, or normocytic
|
|
|
Normal hemoglobin level for men
|
14 to 18 g/dL
|
|
|
Normal hemoglobin level for women
|
12 to 16 g/dL
|
|
|
Average life spans of RBC
|
120 days
|
|
|
Principal function of Erythrocytes
|
Transport oxygen and carbon dioxide
|
|
|
Production in erythrocytes takes place in
|
Red bone marrow, in the vertebrae, ribs, sternum, and proximal ends of the humerus and femur
|
|
|
Erythropoiesis
|
Process of RBC production
|
|
|
Hematocrit
|
Measure of the packed cell volume of RBCs, expressed as a percentage of the total blood volume.
|
|
|
Leukocytes
|
WBCs. Have nuclei, colorless, and live from a few days to several years.
|
|
|
Number of WBCs
|
5000 to 10,000/mm^3 of blood
|
|
|
Two broad categories of WBCs
|
Granulocytes and nongranulocytes
|
|
|
Three types of granulocytes
|
Neutrophils, eosinophils, and basophils
|
|
|
Differential white blood cell count
|
Examination in which the different kinds of WBCs are counted and reported as percentages of the total examined
|
|
|
Wrights stain
|
A chemical solution
|
|
|
Neutrophils
|
Granular circulating leukocytes essential for phagocytosis
|
|
|
Primary phagocytic cells involved in acute inflammatory response
|
Neutrophils
|
|
|
Mature neutrophil
|
Segmental neutrophil "seg"
|
|
|
Normal value of neutrophils
|
60% to 70%
|
|
|
Bands
|
Immature neutrophils
|
|
|
Bandemia
|
Increase in the number of band neutrophils
|
|
|
Eosinophils
|
WBCs that play a role in allergic reactions, effective against certain parasitic worms
|
|
|
Normal values of eosinophils
|
1% to 4%
|
|
|
Basophils
|
WBCs that are essential to the nonspecific immune response to inflammation because they release histamine (vasodilator) during tissue damage or invasion
|
|
|
Normal values of basophils
|
0.5% to 1%
|
|
|
Monocytes
|
WBCs that function like neutrophils; circulatr in the bloodstream and move into tissue, engulfing antigens and cell debris
|
|
