Lab 1: Blood A&P Flashcards
What do the formed elements look like under a microscope?
Erythrocytes are anucleate and very abundant. They may appear white in the center.
Platelets are cell fragments and look like tiny purple dots
Leukocytes have nuclei and are many different colors
Why are leukocytes called white and what are the two categories?
They are called white because they do not contain Hb.
Granular: have granules, little speckles
Agranular: no granules
How do you identify the different types of granular leukocytes?
Look at the granules
Neutrophils: Segmented nuclei, granules are light purple-pink
Eosinophils: Bi-lobed nuclei, granules are reddish (like RBC)
Basophils: 1-2 lobed nuclei, granules are blue-purple granules (bluberries)
How do you identify the different types of agranular leukocytes?
Look at the size and the nuclei
Lymphocytes: Size: small, Nuclei: huge round/oval, darker cytoplasm & nuclei
Monocytes: Size: huge, Nuclei: C-shaped & paler (fat C nuclei)
What determines blood type?
The types of antigens and antibodies an individual has.
What is an antigen and what are the different types?
Protein on the membrane of a cell.
A, B, and Rh
What is an antibody, what does it do, and what are the different types?
Protein in plasma that attacks certain antigens. When the antigen and antibody matches the antibody causes the RBC to agglutinate (clump)
A, B and Rh –Rh antibodies are only made on exposure
What are the most abundant and least abundant leukocytes?
Most abundant: neutrophils and lymphocytes
Least abundant: monocytes, eosinophils, and basophils
What does blood receiving rely on?
Blood reception relies on the your antibodies not matching antigens on the doner’s blood.
What does blood donation rely on?
Blood donation relies on the recipients’ antibodies not matching the antigens on the doner’s blood.
In an A-blood type individual what antigens and antibodies would they have? Who can they donate blood to or receive blood from?
Antigens: A
Antibodies: B
Can donate to: A, AB
Can receive blood from: A, O
In a B-blood type individual what antigens and antibodies would they have? Who can they donate blood to or receive blood from?
Antigens: B
Antibodies: A
Can donate to: B, AB
Can receive from: B, O
In an AB-blood type individual what antigens and antibodies would they have? Who can they donate blood to or receive blood from?
Antigens: A & B
Antibodies: Neither
Can donate to: AB
Can receive from: A, B, AB, O (Universal recipient)
In an O-blood type individual what antigens and antibodies would they have? Who can they donate blood to or receive blood from?
Antigens: Neither A nor B
Antibodies: Both A & B
Can Donate to: A, B, AB, O (universal doner)
Can receive from: O
In a Rh+ -blood type individual what antigens and antibodies would they have? Who can they donate blood to or receive blood from?
Antigens: Rh
Antibodies: Will not create Rh antibodies
Donate to: Rh+
Receive from: Rh+, Rh-
