Flashcards in Blood (FINAL) Deck (66):
1

Erythrocytes

4.5-5 million cells/mm3
Transport oxygen and carbon dioxide 

2

Leukocytes

4,000-11,000 cells/mm3 
Two subtypes: Granulocytes and Agranulocytes

3

Granulocytes

Neutrophils
Eosinophils
Basophils 

4

Neutrophils

40-70% of leukocytes 
Fxn: Phagocytize bacteria 

5

Eosinophils

1-4% of leukocytes 
Fxn: Kill parasitic worms 

100-400 cells/mm3 (µl) blood

6

Basophils

< 1% of blood

Fxn: Prevents clotting (contains heparin, anti-coag), vasodialator (releases histamine). 

Elevated in inflammatory response of allergic reactions.

7

Agranulocytes

Lymphocytes
Monocytes

8

Lymphocytes

20-49% of leukocytes 

1500-3000 cells/µl blood


Fxn: Produce antibodies, destroy virally infected cells, and cancer cells 

 

9

Monocytes

4-8% of leukocytes

100-700 cells/µl blood

Fxn: Phagocytosis  

10

Platelets

250,000-500,000/mm3 
Important for blood clotting 

11

Plasma

55% total blood volume
Proteins: Albumin, fibrinogen, globulins
92% water
Fxn: Solvent for clotting, defense and gas transport. pH and osmotic balance, transportation of nutrients, waste, hormones, etc. 

12

Anemia

Anemia results from a lack of red blood cells or dysfunctional red blood cells in the body. This leads to reduced oxygen flow to the body's organs. 

Possible causes include low iron, low vitamin B, blood loss, reduced blood formation. 

13

Polycythemia

An abnormally increased concentration of hemoglobin in the blood, through either reduction of plasma volume or increase in red cell numbers. 

It may be a primary disease of unknown cause, or a secondary condition linked to respiratory or circulatory disorder or cancer.

14

Leucopenia

A reduction in the number of white cells in the blood, typical of various diseases.

15

Leukocytosis

An increase in the number of white cells in the blood, especially during an infection.

16

Leukemia

A cancer of blood-forming tissues, hindering the body's ability to fight infection.

17

Thrombocytosis

Thrombocytosis is a disorder in which your body produces too many platelets (thrombocytes), which play an important role in blood clotting. The disorder is called reactive thrombocytosis or secondary thrombocythemia when it's caused by an underlying condition, such as an infection.

18

Thrombocytopenia

Thrombocytopenia is a condition in which you have a low blood platelet count. 

It often occurs as a result of a separate disorder, such as leukemia or an immune system problem. Or it can be a side effect of taking certain medications
