Blood does not

produce plasma hormones

the buffy coat doesnt contain


hematocrit is __ of the total blood volume


__ is not found in plasma


__ is a protein not commonly found in plasma


__ is the most abundant protein in plasma


__ would not decrease colloid osmotic pressure (COP) in blood

a diet predominantly based on red meat

serum is essentially identical to plasma except for the absence of


tissues can become edematous (swollen) when

there is a dietary protein deficiency

myeloid hemopoiesis in adults happens in the

red bone marrow

the viscosity of blood is due more to __ than to any other factor


erythrocytes transport oxygen and serve to

transport carbon dioxide

most oxygen is transported bound to

heme groups in hemoglobin

if all the 280 million molecules of hemoglobin contained in RBCs were free in the plasma,

it would significantly increase blood osmolarity

an increased erythropoietin (EPO) output by the kidneys would lead to all of the following except

increased hypoxemia

many RBCs die in the

spleen and liver

all these can lead to polycythemia except

iron deficiency

__ is more likely to cause anemia than any of the other factors below.

renal insufficiency

anemia has these potential consequences except

blood viscosity is increased

what is the final product of the breakdown of the organic nonprotein moiety of hemoglobin


correction of hypoxemia is regulated by

a negative feedback loop

a deficiency of __ can cause pernicious anemia

vit B12

sickle-cell disease is not

a cause of malaria

the ABO blood group is determined by __ in the plasma membrane of RBCs


type A blood can safely donate RBCs to __ and can receive RBCs of type __


Type AB blood has __ RBC antigens

A and B

RhoGAM is an antibody given to RH- women who give birth to a RH+ child. RhoGAM is what type of plasma protein

gamma globulin

the universal donor is

0, RH -

an individual had type B, Rh+ blood. The individual has __ antigens and can produce __ Antibodies

B and D; A

the main reason why an individual AB, Rh- cant donate blood to an individual A, Rh+ is because

Anti-B antibodies in the recipient will agglutinate RBCs of the donor

A woman's first pregnancy is normal but her second pregnancy results in hemolytic disease of the newborn (HDN), or erythroblastosis fetalis. The second child needed a transfusion to completely replace the agglutinating blood. The mother is most likely type ___ and both children are most likely ____.

A, Rh-negative; B, Rh-positive

these are the least abundant formed elements


these are the most abundant agranulocytes


differential count of __ typically increases in response to bacterial infections


__ aid in the bodys defense processes by secreting histamine (vasodilator) and heparinn (anticoagulant)


leukopoiesis begins with the differentiation of

pluripotent stem cells (PPSCs)

some lymphocytes can survive for


a total count above __ WBCs is called leukocytosis


all these can cause leucopenia except


this figure shows the formed elements of blood. What does 7 represent


platelets do Not secrete


the cessation of bleeding is specifically called



initiates the extrinsic pathway of coagulation

when a clot is no longer needed, fibrin is dissolved by


all of these prevent the spontaneous formation of a clot except

the presence of tissue thromboplastic

platelets release__, a chemical vasoconstrictor that contributes to the vascular spasm


the structural framework of the blood clot is formed by

a fibrin polymer

most strokes and heart attacks are caused by the abnormal clotting of blood in an unbroken vessel. Moreover, a piece of the __ clot may break loose and begin to travel in the bloodstream as an __

thrombus; embolus

__ participates in the extrinsic mechanism only


most clotting factors are synthesized in the
