- basophils
Agranulocytes:
- lymphocytes
- monocytes
What are characteristics of neutrophils? correct answers Most abundant leukocyte with multi
lobed nuclei (up to 5 lobes)
What are characteristics of eosinophils? correct answers Contain red or pink granules in
cytoplasm with bilobed nuclei- two lobes connected by a strand
What are characteristics of basophils? correct answers Least abundant leukocyte with bilobed
nuclei and contains blue violet granules
What are characteristics of lymphocytes correct answers Large round nuclei
What are characteristics of monocytes? correct answers Large kidney shaped nuclei
What makes up erythrocytes (RBCs)? correct answers 4.2-6.2 million per cubic mm
What are WBCs responsible for? correct answers Initiating an immune response
If you have type A antigens on your RBCs, and you receive anti-B antibodies, what will happen
in your blood smear? correct answers There will be no agglutination
If you have type A antigens on your RBCs and you receive anti-A antibodies, what will happen
in your blood smear? correct answers There will be agglutination
Blood type A
>> antigens on RBC
>> antibodies in plasma
>> can receive blood from
>> can donate blood to correct answers >> antigen A
>> anti-B antibody
>> can receive type A & O
, >> can donate to A & AB
Blood type B
>> antigens on RBC
>> antibodies in plasma
>> can receive blood from
>> can donate blood to correct answers >> antigen B
>> anti-A antibody
>> can receive from B & O
>> can donate to B & AB
Blood type O

>> no antibodies present
>> can receive blood from all ABO types
>> can donate blood to only AB blood types
What are antibodies? correct answers Produced by B lymphocytes in response to exposure to
foreign antigens. Reduced into the blood plasma and bind specifically to the inducing antigen
How many antigen-binding sites are there per antibody? correct answers Two
What is a single hemoglobin molecule composed of? correct answers 4 protein subunits (globins:
2 alpha, 2 beta chains) each containing a heme group that holds a single iron ion in its center
What is a hemoglobinometer? correct answers Easy to use diagnostic tool to measure
hemoglobin levels within the blood.
What units are hemoglobin levels measure in? correct answers Grams per 100 mL
What are typical range of values of hemoglobin for men and women? correct answers Men: 13-
18 gm%
Women: 11-16 gm%
