What are antibodies?
Y-shaped proteins that identify pathogens and foreign material throughout the body
|
What is a neutrophil?
The most abundant of the WBCs
|
What is clotting?
The bloods most effective defense against bleeding.
|
What is hematocrit?
The percentage of whole blood volume composed of RBCs.
|
What is anemia?
Disorder in which there are not enough red blood cells present in the blood.
|
|
What is agglutination?
When an antibody molecule binds two or more antigen molecules and sticks them together forming an antigen- antibody complex
|
What are neutrophils, eosinophils, and basophils?
The three granulocytes
|
What is positive?
The type of feedback loop blood clotting is considered.
|
What is hemoglobin?
The protein that oxygen binds to on the RBC.
|
What is Sickel-cell anemia?
Disease in which C-shaped cells block and clog capillaries and do not transport oxygen well.
|
|
What is an antigen?
Complex molecules such as proteins, glycoproteins, and glycolipids that are genetically unique to every individual and are found on the surface of red blood cells
|
What are lymphocytes?
These WBCs secrete antibodies, provide immune memory, destroy cancer cells, and coordinate the actions of other immune cells.
|
What are vascular spasm, platelet plug formation, and coagulation?
The three stages of hemostasis.
|
What is erythropoiesis?
The process of RBC production.
|
What is primary polycythemia?
Disorder in which there is an excrete of RBCs present in the blood due to cancer of the red bone marrow.
|
|
What is the Rh blood group?
The blood group determined by the absence or presence of the D antigen on RBCs
|
What are eosinophils?
These white blood cells contain large, rosy-orange granules and a bilobed nucleus.
|
What is an extrinsic mechanism?
The blood clotting mechanism that is initiated by clotting factors that are released by the damaged blood vessel and perivascular tissues.
|
What is erythropoietin?
The hormone released by the liver and kidneys when hypoxemia is detected.
|
What is secondary polycythemia?
Disease that can be caused by dehydration. Water is lost from the blood stream while RBCs remain in the blood and become abnormally concentrated.
|
|
What is hemolytic disease of a newborn?
The disease that occurs when an Rh- woman is exposed to Rh+ blood, begins producing D antibodies, becomes pregnant with an Rh+ fetus, and the D antibodies agglutinate the fetal erythrocytes.
|
What are histamine and heparin?
The two main compounds secreted by basophils.
|
What is platelets degranulation?
The exocytosis of the platelets granules and the release of factors that promote hemostasis.
|
What is hemolysis?
The rupture of RBCs that releases hemoglobin and leaves and empty plasma membrane.
|
What is hemorrhagic anemia?
Anemia caused by blood loss.
