Flashcards in blood typing Deck (16):
1

what is the question you need to ask about blood typing?

will the surface antigens of the donor cells react with the antibodies of the recipient?

2

what occurs if there is a rxn btwn the surface antigens in the donor with the antibodies of the recipient?

agglutination

3

What type of blood has an A antigen and a B antibody (agglutinin)?

type A

4

what type of antigen and antibody does type B blood have?

B surface antigen
A agglutinin (antibody)

5

what type of antigen and antibody does type AB blood have?

A and B surface antigen

6

what type of blood has no surface antigen? what is its antibody (agglutinin)

type O has no surface antigen and A and B agglutinin

7

what blood type is the universal donor?

O type has no surface antigens therefore there cannot be a rxn between the donor surface antigens and the recipient's antibodies

8

what blood type is the universal receptor?

AB has no antibodies so it is unable to react to any surface antigens

9

what is the basic composition of blood?

formed elements and plasma

10

what are the formed elements of blood?

erythrocytes, leukocytes and platelets

11

what is the hematocrit?

% of blood comprised of RBC

12

what is plasma made of

92% h2o
8% solutes

13

what are some of the solutes in plasma?

proteins like
albumin
fibrinogen
globulins

14

the O2 carrying capacity of the blood is directly dependent on the concentration of what?

erythrocytes

15

what is the concentration of erythrocytes and leukocytes in the blood?

RBC 4.5-5.5 million per cc
WBC 5000-9000 per cc

16

what does the term blood type refer to?

the type of antigens present on the RBC membranes
