Blood Flashcards
What’s the composition of blood
1-plasma
2-blood cells
3-platelet
What’s the function of red blood cells
Are responsible for carrying oxygen from and to tissues
What’s the presentage of plasma and cell of blood in blood
cells make up about 45%, plasma make up about 55%
About 90%of plasma is water true or false
True
What’s the composition of 10%of plasma
Proteins, inos, wastes, nutrients, and dissolved gases
The ions and proteins and other molecule what’s the functions
1-maintaining blood PH
2-maintaining osmotic pressure
What’s the other compounds in the blood
1-hormones
2-antibodies
3-lipids
What’s the shape of erythrocyres
Small and bioconcave disc measures with average thickness of 2 micrometer
Cytoskeletal proteins linked by what and reason
Linked by actin to maintaining to shape
What the compounds responsible for color red of red blood cells
Iron
What’s the number of red blood cells in male and female
In female:- 4.5 - 5 million
In male :- 5 - 5.5 million
What’s the contain of red blood cells
1-Concentrated hemoglobin molecules
2-with absence of internal structure organelles
What is the properties of shape of red blood cells
1-provides 20% - 30% greater surface area thus facilitating gaseous exchange
2-give flexibility and allow erythrocyres to squeeze themselves through small capillaries
What’s Blood group dependent ?
absence or presence antigen on surfaces of red blood cells
What is the functions of leukocyte
1- involved in immunity
2-recognizing and neutralizing
Classification of leukocyte based on
1-The type of cytoplasmic granules
2-thier nuclear morphological
What is the normal count leukocyte
4.000 - 11.000 \ mm³
What is leucocytosis
Increase total leukocyte count above 11.000 \ mm³
what is leucopenia
decrease total leukocyte below 11.000 mm³
What causes leucopenia
Irradiation, prolonged use of certain antibiotics
what is the type of granulocytes
1- specific granules
3-non specific granules
what is the function of specific granules
bind neutral, acidic, basic stained and have specific function
what is the non specific granules, and write second name
is the normal lysosomes, azurophilic granules
what is the other name of neutrophils
Polymorphonuclear
