Blood lecture ch 18
What 3 primary classes are in plasma proteins?
Albumin, globulins, & fibrinogens
A person with type A blood has ______ on the RBC
Anti-A
gama globulins
Antibodies belong to a class of plama proteins called
Process of coagulation
Factor X starts, ends w/ thrombin, converts fibrinogen to fibrin
red bone marrow
In adults, the only site of red blood cell production, and the primary site of white blood cell formation, is the
Dehydration would cause an _____in the hematocrit
Increase
Erythropoietin directly stimulates RBC formation by
Increasing rates of mitotic divisions in erythroblasts, speeding up maturation of RBC, accelerating the rate of hemoglobin synthesis
AB-
It is impossible for a type O+ baby to have a type ______ mother.
What contribution from the intrinsic and extruinsic pathways is necessary for the common pathway to begin?
Must combine Ca2+ and PF-3 to activate factor 10
hemopoiesis
Production of all the formed elements of blood is called ____________.
How would the extended use of antibiotics affect blood clotting?
Release of heparin and histamine by basophils would be spread
Hemolytic disease on the newborn may result if an ____mother carries an Rh positive fetus
Rh negative
thymus and red bone marrow
Stem cells responsible for lymphopoiesis are located in the
fibrinolysis
The complex sequence of steps leading to the conversion of fibrinogen to fibrin is
eosinophils
The differential count of a person who has an allergy would indicate a high number of
thromboplastin
The extrinsic pathway of coagulation is activated by __________ from damaged perivascular tissues.
factor X
The first clotting factor that the instrinsic and extrinsic pathways have in common is
vascular spasm
The first step in hemostasis is
WBCs, RBCs, platelets
The formed elements of the blood include:
erythropoietin
The kidney hormone __________ stimulates RBC production.
homeostasis
The overall cessation of bleeding involving several mechanisms, is called ______________.
hematocrit
The percentage of blood volume composed of RBCs is called the ___________.
How do RBC differ from typical cells in the body?
They are 99.9% of total elements, they have no nucleus, ribosomes, or mitochondria
How do platelets help the clotting process
They form a temperature patch in the walls of damaged blood vessels to slow the rate of blood loss.Filaments shrink and the clot reduces size of the brake in the vessel wall
What 5 major fuctions are performed by blood?
Transportation, regulation of pH & ion concentrations , reduce fluid loss from injuries,defense, stabilize body temp
True
True or False? A man with blood type A+ and a woman with blood type B+ could have a baby with type O-.
True
True or False? By volume, the blood usually contains more plasma than blood cells.
True
True or False? Calcium ions are required for blood clotting.
serum
When the clotting proteins are removed from plasma, __________ remains.
agglutination
Which is not a component of hemostasis?
