NEVER LET MONEYS EAT BANANAS
eosinophils correct answers •granulocyte
•reddish granules
•bi-lobed nucleus
basophils correct answers •granulocyte
•least abundant
•dark blue-violet granules
lymphocytes correct answers •agranulocyte
•little cytoplasm surrounding nucleus
•round, dark nucleus
monocytes correct answers •agranulocyte
•kidney-shaped nuclei, lighter stained
•more cytoplasm surrounding nucleus
platelet correct answers
type A blood correct answers •has type A antigens on surface of RBC
•person has type B antibodies
•can receive type A, O
•donate to type A, AB
, •agglutination if type B, AB
universal recipient correct answers type AB
universal donor correct answers type O
Rh factor correct answers •Rh surface antigen = surface antigen D
•if agglutination of sample --> positive!
-i.e. A+, AB+
hemolytic disease of the newborn correct answers •occurs in Rh- mothers carrying Rh+ children
•mother has antibodies against Rh+ because she is Rh-
•mother given RhIg (immunoglobulin)
-prevents sensitization to D antigen
-binds with fetal RBC with Rh+ before mother can product anti-Rh response
hemagglutination correct answers •pre-formed antibodies opposite to person's blood type bind to
antigens on foreign blood and stick together
•can block blood vessels
antibodies correct answers produced by B lymphocytes in response to exposure to foreign
antigens
centrifuge loading correct answers sealing clay facing out and all balanced
hemoglobinometer correct answers •measures amount of hemoglobin in blood
•set to 540 nm
-highest point of intersection
-measuring total hemoglobin conc
•measured as grams per 100 mL
•11-16% for women
•13-18% for men
hematocrit correct answers •fraction of whole blood volume that is made up of RBC
•47 +/- 7% for men
•42 +/- 5% for women
effects on hemoglobin and hematocrit levels correct answers •dehydration
-Hb same
-hematocrit up
•polycythemia
-both up
•living at high altitude
-both up
•anemia
-both down
