hormone ________ which is mostly produced
in the ________.
When a person who lives at sea level vacations in the Rocky Mountains, what would you expect in his/ her blood?
The release of erythropoietin, an increase in red blood cell production, a drop in
Oxygen levels, and a rise in hematocrit
Erythropoiesis is stimulated when
blood flow to the kidney declines.
Hormones called ________ are involved in regulation of white blood cell populations.
colony- stimulating factors
The ________ is a procedure that is used to determine the number of each of the various types of white blood cells.
The ________ is a procedure that is used to determine the number of mature erythrocytes.
________ transport(s) oxygen and CO2 in the RBCs.
The function of red blood cells is to carry..........
Oxygen to cells and carbon dioxide away
RBCs typically live about 120 days. The main reason for this short lifespan in RBCs is due to ............
lack of nucleus
In adults, erythropoiesis exclusively takes place in
red bone marrow
The process of red blood cell production is called
The developmental stage at which erythrocytes enter the circulation is as
A person with Type A blood has t........type of antibody on RBCs and ......... type of antibody in plasma?
Rb proteins/ B
If the blood types of a donor and recipient are compatible, then
there is no reaction between antibodies and antigens.
People with type AB blood are considered the "universal recipient" for transfusions because
there Blood lacks a or b agglutinins
Bill wants to determine his blood type, so he takes a few drops of blood from a puncture wound in his finger and mixes it with various antisera. His blood cells agglutinate when mixed with the anti-A sera but not with the anti-B or anti-D sera. What do you know about Bill's Rh Antibody?
Bills plasma contains B antibodies
Hemolytic disease of the newborn may result if
an Rh-negative mother carries an Rh-positive fetus

Often elevated in allergic Individuals
The most numerous white blood cells in peripheral circulation are the
White blood cells that release histamine at the site of an injury are
During a bacterial infection you would expect to see increased numbers of........
________ involves a cascade of reactions leading to the conversion of fibrinogen to fibrin.
The conversion of fibrinogen to fibrin is catalyzed by
Which of the following vitamins is needed for the formation of clotting factors?
_______ is a condition in which the oxygen-carrying capacity of the blood is reduced.
Whole blood for testing in a clinical laboratory is usually collected from......artery/vein?
Eileen is a strict vegan and therefore eats no animal products. She develops an anemia that her doctor thinks is caused by a nutritional deficiency. Which of the following is the likeliest candidate?
Vitamin B12 deficiency
A cancer involving neutrophils, eosinophils, or basophils is called a
Pernicious anemia caused by a lack of intrinsic factor is specifically treated by..
injections of vitamin B12
A condition where pathogens are present and multiplying in the blood is called....
The percentage by colume of packed red blood cells in a given sample of blood after centrifugation
Which specific plasma proteins would you expect to be elevated during an infection?
a stem cell for blood-cellular elements especially : one considered competent to produce all types of blood cells.
Compare the types of cells that lymphoid stem cells and myeloid stem cells produce.
Lymphoid cells- originate in the red bone marrow and give rise to lymphocytes; these stem cells also produce
lymphocytes in the thymus, spleen, and lymph nodes.
Myeloid stem cells- are cells in red bone marrow that give rise to all the formed elements except lymphocytes.
What is hematology?
study of blood
Which condition would a patient have if she had a depressed hematocrit level?
Hemoglobin is a protein composed of four globular subunits, each bound to a heme molecule, which gives red blood cells the ability to transport oxygen in the blood.
What is determined by the surface antigens on RBCs?
Which blood type(s) can be safely transfused into a person with type O-blood?
Only type O
Why can't a person with type A blood safely receive blood
from a person with type B blood?
If a person with Type A blood receives a transfusion of Type B blood, which contains anti-A antibodies, the
red blood cells will agglutinate (clump), potentially blocking blood flow to various organs and tissues.
Define hemolytic disease of the newborn (HDN).
a blood problem in newborn babies. It occurs
when your baby's red blood cells break down at a fast rate.
Does an Rh+ mother carrying an Rh‒ fetus require a RhoGAM injection? Explain your answer.
An Rh+ mother carrying an Rh- fetus does not require a RhoGAM injection because the fetus
is not at risk of Rh incompatibility. The fetus is not at risk because its RBCs lack Rh surface
antigens, and the mother's plasma lacks anti-Rh antibodies.
Identify the five types of white blood cells.
neutrophils, eosinophils, basophils, monocytes, lymphocytes
stoppage of bleeding
Compare pernicious anemia with iron deficiency anemia.
Pernicious anemia is insufficient red
blood cell production that results from a lack of vitamin B12; the blood cells that do develop
tend to be macrocytic (excessively large) and abnormally shaped.
Iron deficiency anemia results when the dietary intake or absorption of iron is insufficient,
impairing normal hemoglobin synthesis; these blood cells are microcytic (abnormally small).
Identify the two types of leukemia
The two types of leukemia are myeloid leukemia and
