Blood Flash Cards

QuestionAnswer
Whole blood is made of what 2 components? Blood plasma and formed elements.
Blood plasma is made of what 3 components? proteins, water, and other solutes.
What are the 3 main proteins found in blood? albumins, globulins, and fibrinogen.
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, white blood cells, and platelets.
What are the 5 classes of formed elements? neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
Relationship between erythrocyte and erthropoesis. the creation of erythrocytes is called erythropoesis.
Relationship between reticulocytes and red blood cells. near the end of erythropoesis, red blood cell ejects its nucleus and becomes a reticulocyte.
Role of a neutrophil. help protect the body against infections by killing and ingesting bacteria, fungi, and foreign dubris.
Role of a monocyte. ingest dead or damaged cells and help defend against many infectious organisms.
Role of an eosinophil. kill parasites, destroy cancer cells, and are involved in allergic responses.
Role of a basophil. also participate in allergic responses.
Role of B, T, and natural killer cells. T and natural killer cells protect against viral infections, detect and destroy some cancer cells. B cells develop into cells that produce antibodies.
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 does vascular spasm aid in hemostasis? reduces blood loss for several minutes-hours, allowing other hemostatic mechanisms to begin.
How does platelet plug formation aid in hemostasis? they come together to form a platelet plug that helps fill the gap in the injured blood vessel wall.
What is the difference between a thrombus and an embolus? A thrombus is the clot itself, and the embolus is a blood clot, bubble of air, fat from a broken bone, or a piece of debris.
What is a pulmonary embolism and why is one dangerous? the presence of a blood clot that gets in the way of circulation to blood tissue. Can block the blood to the heart, brain, and kidney.
What makes on blood group different from another? the presence or absence of various isoantigens.
How is type A blood different from type blood B blood? A blood has A antigens, B blood has B antigens.
How is type AB blood different from types A and B blood? AB blood carries both A and B antigens.
What does an anti-A antibody do? Anti-B antibody? Anti-A reacts with antigen A, and anti-B reacts with antigen B.
Who has an anti-A antibody? Type B and Type O have it, type A and type AB do not.
Who has an anti-B antibody? Type A and Type O have it, type B and type AB do not.
What happens in an incompatible blood transfusion? antibodies in plasma bind to antigens on RBC's. Causes hemolysis and release hemoglobin into plasma.
What is the difference between Rh+ and Rh- blood? If they have the RH antigen there Rh+, if they dont there Rh-.
What is anemia and what are the symptoms of anemia? The oxygen-carrying capacity of blood is reduced. Symptoms - fatigue, paleness, and low content to cold.
What is the cause of iron-deficiency anemia? Inadequate absorption of iron.
What is the cause of pernicious anemia? Insufficient hemopoiesis.
What is the cause of hermorrhagic anemia? Excessive loss of RBC's through bleeding.
What is the cause of hemolytic amemia? RBC plasma membranes rapture prematurely.
What is the cause of thalassemia? an abnormalty in one of the 4 polypeptide chains of hemoglobin.
What is the cause of aplastic anemia? destruction of the red bone marrow.
What are the causes and symptoms of sickle cell anemia? Cause - an abnormal kind of hemoglobin Symptom - creation of sickle cells, eventually tissue damage
What are the causes and symptoms of hemophilia? Cause - deficiency of clotting which bleeding may occur Symptom - nosebleeds, blood in urine, painful joints, and tissue damage
What are the causes and symptoms of leukemia? Cause - uncontrolled production and accumulation of immature keukocytes Symptom
Reticylcyte counting the volume of reticulocytes in a sample of blood measures rate of erythropoesis.
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 manufacture of WBCs.
Complete blood count measure volume of all blood components, measures blood components that are out of range.
