Blood

Question 1

What whole blood consists of

Answer 1

Plasma (fluid portion of blood) and formed elements (cellular part of the blood): Erythrocytes (RBC)+leukocytes (WBC)+platelets

Question 2

Plasma consists of

Answer 2

water, proteins, other solutes such as nutrients and ions

Question 3

% of blood is plasma

Answer 3

55%

Question 4

% of blood is formed elements

Answer 4

45%

Question 5

WBC/leukocytes 2 subclasses are

Answer 5

granulocytes and agranulocytes

Question 6

Granulocytes

Answer 6

WBC that have cytoplasmic granules that are visible when stained

Question 7

Different granulocytes

Answer 7

Neutrophils, eosinophils and basophils

Question 8

different agranulocytes

Answer 8

lymphocytes and monocytes

Question 9

WBC Most->least

Answer 9

Neutrophils, lymphocytes, monocytes, eosinophils, basophils

Question 10

neutrophil recognition

Answer 10

multilobed nuclei, most numerous WBC, also called polymorphonucleocytes

Question 11

Eosinophils recognition

Answer 11

tend to have Bilobed nuclei: reacts to eosin(red dye)

Question 12

Basophils recognition

Answer 12

Granules appear dark blue-purple, difficult to find due to being least numerous WBC. interacts strongly with hematoxylin (basic dye dark purple stain)

Question 13

Lymphocyte recognition

Answer 13

Smaller than granulocytes and have a large spherical nuclei. second most common WBC

Question 14

Monocyte recognition

Answer 14

largest WBC have U shaped nuclei. 3rd most numerous

Question 15

Platelets

Answer 15

Small cellular fragments with no nuclei and missing most organelles. used for blood clotting

Question 16

blood clotting is due to

Answer 16

platelets

Question 17

Blood typing is done by

Answer 17

checking the blood for the presence or absence of specific antigens/glycoproteins on the cell surface

Question 18

Most common blood types

Answer 18

O+, A+,B+

Question 19

What antigens does O blood have

Answer 19

None, it has neither A or B

Question 20

How are antigens determined to be on a erythrocyte

Answer 20

by combining them with an antiserum solution that will clot/agglutination. Antibodies in the serum cause antigens on erythrocytes to agglutination

Question 21

Blood with RH antigen is considered

Answer 21

positive

Question 22

blood without RH antigen is considered

Answer 22

negative

Question 23

Hemolysis

Answer 23

When recipients antibodies agglutinate foreign erythrocytes and the immune system destroys them. wrong blood given to a recipient causes hemolysis when the recipients immune system recognizes it as foreign.

Question 45

Why is the O- the universal donor

Answer 45

it has no antigens and will not trigger an immune response

Question 46

Why is AB+ the universal recipient

Answer 46

has all 3 antigens and no antibodies to the antigens
