appearance: light blue granules in acid based stain, lobed nucleus
percentage: 50-70% leukocytes

Question 2

Basophils

Answer 2

appearance: deep blue granules from basic stain

percentage: less than 1% of leukocytes

Question 3

Eosinophils

percentage: 2 - 4% of leukocytes

Question 4

Answer 4

largest blood cell, leave bloodstream to become macrophages
appearance: kidney-shaped or oval nuclei

percentage: 3-8% of leukocytes

Question 5

Answer 5

appearance: about the size of RBC, large spherical nuclei, thin rims of cytoplasm

percentage: 25-45% of leukocytes

Question 6

Antigens

Answer 6

glycoproteins on cell membrane that can “potentially”. trigger an immune response (agglutinogens)

Question 7

Antibody

Answer 7

protein that binds “specifically” to a particular antigen (agglutinins)

Question 8

Type AB

Answer 8

Universal recipient: People with AB blood have no antibodies to A, B, or Rh antigens in their blood. AB antigens.

Question 9

Type O

Answer 9

Universal Donor: no antigens presents so they can donate without transfusion issues, A and B antibodies.

Question 10

Type A

Answer 10

A antigens, B antibodies

Question 11

Type B

Answer 11

B antigens, A antibodies

Question 12

Rh+

Answer 12

Rh antigens present, no antibodies

Question 13

An Rh- mother has an Rh+ baby

Answer 13

Mother (Rh-):
Antigens: No Rh antigens
Antibodies: May develop anti-Rh antibodies after exposure during pregnancy or delivery.
Baby (Rh+):
Antigens: Rh antigens present on RBCs
her antibodies can cross the placenta and attack the baby’s Rh+ RBCs, leading to hemolytic disease of the newborn

Question 14

Rh-

Answer 14

no Rh antigens, anti-Rh antibodies
