The blood represents ___ % of total body weight
8
- 5 liters in women
- 5.5 liters in men
Erythrocytes function
Red Blood Cells
- important in O2 and CO2 transport to body tissue
Leukocytes function
White Blood Cell
- immune systems mobile defence units
EXAMPLE: antibodies
Thrombocytes
platelets
- important in hemostasis (blood clotting)
Plasma represent __% of whole blood and its total weight
65

45
Eosinophilis function
Leukocyte
- attack parasitic worms; important in alergric reactions
Monocytes function
Leukocytes
- in transit to become tissue macrophages
types of lymphocytes
- B Lymphocytes
- T Lymphocytes
B lymphocytes function

hematocrit values in females
42%
hematocrit values in men
45%
average pl. volume in blood females
58%

55%
Plasma composition
- 90% water
- 1% inorganic molecules
- 6-8% plasma proteins
Albumins
- most abundant
- contribute to pl. colloid osmotic pressure
- transport many poorly soluable substances in the plasma
three plasma proteins
- albumins
- globulins
- Fibrinogens
Albumins examples
- bilirubin
- penicillin
- bile salts
Globulins
- exsists in three forms
- three units bind and transport many substances, such as TH, iron, and cholerstrol in the plasma
Alpha and Beta globulins
- transport many water- insoluble substances; clotting factors; inactive precursor molecules
Gamma Globulins
- antibodies
