PNB 2265 Exam 1 || 100% Accurate Answers.
What kind of tissue is blood? correct answers Fluid connective tissue
What is hemostasis? correct answers Blood clotting
What is plasma made up of? correct answers Primarily water
What is the supernatent of blood? correct answers Plasma
What is the pellet in blood? correct answers Red blood cells
Thrombocytes correct answers Platelets
Leukocytes correct answers White blood cells
Erythrocytes correct answers Red blood cells
Hematocrit correct answers Measurement of the percentage of red blood cells in blood
composition
Where are the white blood cells and platelets found in a hematocrit? correct answers Buffy coat
What does HBG stand for in CBC? correct answers Hemoglobin
What does MCV measure? correct answers Mean corpuscular volume of red blood cells
What are the subtypes of WBC? correct answers neutrophils
lymphocytes
monocytes
eosinophils
basophils
What type of WBC do you look for to be abnormal for HIV? correct answers Lymphocytes
What is a mnemonic to remember WBC in descending proportion? correct answers Never let
monkeys eat bananas
What is the most abundant formed element in blood? correct answers Red blood cells
Describe the structure/function relationship in red blood cells correct answers 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 answers grams/deciliter
, How many protein subunits make up hemoglobin? correct answers 4
What chains are in adult hemoglobin? correct answers 2 beta chains and 2 alpha chains
What chains are in fetal hemoglobin? correct answers 2 alpha chains and 2 gamma chains `
How many heme groups on in hemoglobin? correct answers 4, one on each chain
Where does oxygen bind to? correct answers The iron in the heme group on hemoglobin
What is the hemoglobin chain called when nothing is bound to it? correct answers
Deoxyhemoglobin
What is the hemoglobin chain called when oxygen is bound to it? correct answers
Oxyhemoglobin
What is the hemoglobin chain called when carbon dioxide is bound to it? correct answers
Carabino-hemoglobin
Is the binding of gas to each hemoglobin chain independent? correct answers 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 answers Bohr and Haldan effect
Haldan Effect correct answers 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 answers 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 answers Any situation when the blood fails to oxygenate tissues
Microcytic Anemia correct answers Smaller than normal red blood cell size
What type of anemia occurs when the MCV is low? correct answers Microcytic anemia
What are two types of microcytic anemia? correct answers 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 answers Microcytic anemia
What kind of anemia is caued by an iron deficiency? correct answers Microcytic anemia
Macrocytic Anemia correct answers Larger than normal RBC
What kind of tissue is blood? correct answers Fluid connective tissue
