Blood plasma is made of what 3 componets? protein 7%, water 91.5%, and other solutes 1.5%
What are the 3 main proteins found in blood? albumins 54%, globulins 38%, and fibrinogen 7%
What are the 6 solutes commonly found in blood? electrolytes, nutrients, gases regulatory substances, vitamins, and waste products
What is the definition of a formed element? red blood cells, WBC's, and platelets
The 3 classes of a formed element are: WBC, RBC, and platelets
What are the 5 classes of white blood cells? nuetrophils, lymphocytes, monocytes, eosinophils, and basophils
The relationship between the terms erthythocyte and erythropoesis Near the end of erythropoiesis, an RBC precursor ejects its nucleus and becomes a reticulocyte. Erythrocytes contain hemoglobin and carry oxygen to blood.
the relationship between reticulocytes and red blood cells reticulocytes pass from red bone marrow into the bloodstream
The role of nuetrophil injest other cells
The role of monocyte replinish macrophages and move quickly
The role of eosinphil protect body
The role of basophil prevent blood clot and promotes blood flow to tissues
The role of B, T and natural killer cells B-make antibodies t-protects and reacts to immune system
What is hemostasis? A sequence of responses that stops bleeding when blood vessels are injured.
What are the 3 methods of reduction of blood loss? vascular spasm, platelet plug formation, and blood clotting
What is a hemorrhage? the loss of a large amount of blood from the vessels
How do platelet plug formation aid in hemostasis? can stop bleeding loss completely if the hole in a blood vessel is small enough
How does vascular spasm aid in hemostasis? reduces blood loss for several minuntes to hours during which time the other hemostatic mechanisms begin to operate.
How does clotting aid in hemostasis? prevents blood loss
What is the difference between a thrombus and an embolus? A thrombus is the clot itself and an embolus is a piece of debris transported by the bloodstream
What is a pulmonary embolism and why is one dangerous? The embolus ro become lodges in the lungs. May result in death.
What makes one blood group different from another? the presence or absence if various isoantigens
How is type A blood different from type B blood? Type A-antigen A Type B-antigen B
How is type AB blood different from types A and B? both antigen A and B
What does an anti-A antibody do? What does an anti-B antibody do? Antibody A; A antigens on surface of your RBC Antibody B; plasms in blood stream
Who has an anti-B antibody? who does not? type A, and AB has it. Type O and B doesnt.
Who has an anti-B antibody? who does not? type B and AB has it. Type O and A doesnt.
What happends in an incompatible blood transfusion? antibodies in the recipientd plasma bind to tge antigens on the donated RBC's.
What is the differnce between RH+ and RH- blood? RH+ have RH antigen (positive) RH- lack RH antigen (negative)

What is the cause of iron-deficiency anemia? inadequate absorbstion of iron, excessive loss of iron, or insufficiant intake of iron
What is the cause of pernicious anemia? insufficiant hemopoiesis resulting from an inability of the stomach to produce intrinsic factor
What is the cause of hemorrhagic anemia? excessive loss of RBC's through bleeding resulting from large wounds
What is the cause of hemolytic anemia? inherited defects or from outside agents such as parasites, toxins, or antibodies
What is the thalassemia? populations from countries bordering Med. Sea
What is the cause of aplastic anemia? destruction of the red bone marrow caused by toxins, gamma radiation, and certain medications that inhabit enzymes needed for hemopoisis
What are the causes and symtoms of sickle cell anemia? When HBS given up oxygen to the intersitial fluid, it forms long, stiff, rodlike structures that bend the erythocyte into a sickle shape.
What are the causes and symtoms of hemophilia? blood clotting factors, inherited deficiancy of clotting in which bleeding may occur.
What are the causes and symtoms of leukemia? accumilation of immature leukocytes
Reticylocyte Counting the volume of reiculocytes in a same of blood- meausures rate of erthtopoesis
Hematocrit Counting the % of a blood sample that is composed of RBCs. Diagnoses anemia.
Differential WBC count Count various forms of WBC to assess for infections and manufacure of WBCs
Complete Blood Count Measure volume of all blood componets, measures blood componets that are out of range.
