Hematocrit What is the normal percentage of erythrocytes in blood? 45% Hematocrit measures the percentage of blood volume that consists of what cells? erythrocytes What is the most abundant type of WBC? NEUTROPHILS What WBC is the first to respond to infection? How do they destroy bacteria? NEUTROPHILS Phagocytize bacteria Which WBCs are the ones that primarily destroy the dissolved toxins that bacteria secrete into body fluids? Neutrophils What WBC secretes histamines? What is it called when it leaves the circulation to enter the tissues? BASOPHILS MAST CELL Which WBC fights allergies and parasitic infections, and during these conditions, their numbers increase. EOSINOPHILS What are MONOCYTES called when they leave the circulation and enter the tissues? MACROPHAGES Which WBCs phagocytize bacteria? Monocytes (macrophages) and neutrophils. Do monocytes and neutrophils kill viruses? No What WBC kills viruses? What WBC acts against a specific foreign molecule Lymphocytes (specifically, the also called T-cells) All lymphocytes (B-cells and T-cells) act against a specific foreign molecule. What are the two main classes of lymphocytes? T cells (T-lymphocytes) and B cells (B lymphocytes) Which WBC attacks organs after an organ transplant? T cells lymphocytes,
How do B cells fight infection? by becoming cells that produce antibodies What are the actual cells that produce the antibodies? Plasma cells What are the two main features of mononucleosis? Inflammation of lymph vessels (lymphangitis) Infection of B lymphocytes with the Epstein-Barr virus Which immune system cell type is preferentially destroyed by the AIDS virus? T cells (T-lymphocytes). By secreting hormones, the thymus causes which cells to become active? T cells (T-lymphocytes). Why are most people sick more often as children than as adults in their 20s through 30’s? We build up many varieties of memory lymphocytes during childhood, providing immunity from more and more antigens during adulthood What is a plasma protein involved in blood clotting? fibrin What are platelets responsible for? Blood clotting List the blood cells in order of longevity (life span), from longest—lived to shortest—lived. erythrocytes, platelets, neutrophils What is a condition in which the blood’s capacity for carrying oxygen is diminished? ANEMIA What blood disease is a form of anemia where the RBCs have abnormal hemoglobin that deforms the cells into strange shapes (target cells, spheres, but not sickled) THALASSEMIA Which form of anemia is found especially in the African race; always characterized by sickle-shaped erythrocytes SICKLE CELL DISEASE Which form of anemia is from a single amino acid mutation resulting in a valine amino acid substituted for glutamic acid? SICKLE CELL DISEASE Which form of anemia is characterized by very large erythrocytes? Megaloblastic anemia What type of anemia is from loss of intrinsic factor; a frequent result of gastric bypass surgery? Megaloblastic anemia What type of anemia can occur due to a blood transfusion of mismatched blood? Acquired Hemolytic anemia What type of anemia is it when a person cannot maintain iron in a reduced state? G6PD deficiency What type of anemia is from chronic blood loss? Hemorrhagic anemia What type of disorder of the blood cells causes them to shrink over time due to problems with the red blood cell membrane? Hereditary spherocytosis What disorder of blood is characterized by too few mature white blood cells? LEUKEMIA
