PNB 2265 EXAM 1 QUESTIONS WITH
100% CORRECT VERIFIED ANSWERS .
What kind of tissue is blood? - Correct Answer -Fluid connective tissue
What is hemostasis? - Correct Answer -Blood clotting
What is plasma made up of? - Correct Answer -Primarily water
What is the supernatent of blood? - Correct Answer -Plasma
What is the pellet in blood? - Correct Answer -Red blood cells
Thrombocytes - Correct Answer -Platelets
Leukocytes - Correct Answer -White blood cells
Erythrocytes - Correct Answer -Red blood cells
Hematocrit - Correct Answer -Measurement of the percentage of red blood cells in blood
composition
Where are the white blood cells and platelets found in a hematocrit? - Correct Answer -Buffy
coat
What does HBG stand for in CBC? - Correct Answer -Hemoglobin
What does MCV measure? - Correct Answer -Mean corpuscular volume of red blood cells
1
,What are the subtypes of WBC? - Correct Answer -neutrophils
lymphocytes
monocytes
eosinophils
basophils
What type of WBC do you look for to be abnormal for HIV? - Correct Answer -Lymphocytes
What is a mnemonic to remember WBC in descending proportion? - Correct Answer -Never
let monkeys eat bananas
What is the most abundant formed element in blood? - Correct Answer -Red blood cells
Describe the structure/function relationship in red blood cells - Correct Answer -Red blood
cells are biconcave because they lack a nucleus and organelles. This shape maximizes the
space for CO2 and O2 to diffuse. This shape also allows for efficient movement through
blood vessels.
What unit is hemoglobin measured in? - Correct Answer -grams/deciliter
How many protein subunits make up hemoglobin? - Correct Answer -4
What chains are in adult hemoglobin? - Correct Answer -2 beta chains and 2 alpha chains
What chains are in fetal hemoglobin? - Correct Answer -2 alpha chains and 2 gamma chains `
How many heme groups on in hemoglobin? - Correct Answer -4, one on each chain
Where does oxygen bind to? - Correct Answer -The iron in the heme group on hemoglobin
What is the hemoglobin chain called when nothing is bound to it? - Correct Answer -
Deoxyhemoglobin
2
, What is the hemoglobin chain called when oxygen is bound to it? - Correct Answer -
Oxyhemoglobin
What is the hemoglobin chain called when carbon dioxide is bound to it? - Correct Answer -
Carabino-hemoglobin
Is the binding of gas to each hemoglobin chain independent? - Correct Answer -No, there is
cooperative binding that occurs because when a gas binds to the chain, it changes shape
What are two examples of cooperative binding? - Correct Answer -Bohr and Haldan effect
Haldan Effect - Correct Answer -It is easier for CO2 to bind to hemoglobin if it does not have
oxygen bound to it. This ensures that RBC can remove CO2 from tissues after it delivers
oxygen.
Bohr Effect - Correct Answer -CO2 binding facilitates the release of oxygen. This makes it
easier to release oxygen to tissue when the hemoglobin gets CO2. This is useful for
offloading oxygen
Anemia - Correct Answer -Any situation when the blood fails to oxygenate tissues
Microcytic Anemia - Correct Answer -Smaller than normal red blood cell size
What type of anemia occurs when the MCV is low? - Correct Answer -Microcytic anemia
What are two types of microcytic anemia? - Correct Answer -Thalassemia: hemoglobin
mutation that results in smaller than normal cell size
Iron Deficiency: caused by not enough iron in diet or heavy periods, which can lead to small
RBC because hemoglobin takes up so much weight of a RBC
What kind of anemia is thalassemia? - Correct Answer -Microcytic anemia
What kind of anemia is caued by an iron deficiency? - Correct Answer -Microcytic anemia
