Answer 12

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.

Question 13

Anemia

Answer 13

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.

Question 14

Polycythemia

Answer 14

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.

Question 15

Leucopenia

Answer 15

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

Question 16

Leukocytosis

Answer 16

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

Question 17

Leukemia

Answer 17

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

Question 18

Thrombocytosis

Answer 18

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.

Question 19

Thrombocytopenia

Answer 19

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

Question 20

Leukocytes

Answer 20

4,000-11,000 cells/mm3

Two subtypes: Granulocytes and Agranulocytes

Question 21

Granulocytes

Answer 21

Neutrophils
Eosinophils
Basophils

Question 22

Neutrophils

Answer 22

40-70% of leukocytes

Phagocytize bacteria

Question 23

Eosinophils

Answer 23

1-4% of leukocytes

Kill parasitic worms

Question 24

Basophils

Answer 24

Less than 1% of leukocytes

Release histamine and mediate inflammatory response
