The formed elements of the blood consists of: Red and white blood cells, and platelets Loose connective tissue and cartilage contain a network of incoluble fibers, where as plasma, a fluid connective tissue contains: Dissolved proteins Blood transports dissolved gases, bringing oxygen from the lungs to the tissues and carrying : Carbon dioxide from the tissues to the lungs The "patrol agents" in the blood that defend the body against toxins and pathogens are: White blood cells and antibodies The unique composition of whole blood consists of: Plasma and formed elements In addition to water and proteins, plasma contains: Albumins, globulins, and fibrinogen The three primary classes of plasma proteins are: Albumins, globulins, and fibrinogen The primary function of plasma is: Absorbing and releasing heat, transporting ions and red blood cells The plasma proteins that attack foreign proteins and pathogens are called: Immunoglobulins The fluid left after the clotting proteins are removed from plasma is known as: Serum Formed elements in the blood are produced by the process of: Hemopoiesis The stem cells that produce all the blood cells are called: Hemocytoblasts In adults, the only site of RBC and WBC production is the: Red bone marrow The primary function of a mature red blood cell is: Transport of respiratory gases Circulating mature red blood cells lack: Mitochonfria, ribosomes, and nuclei RBC production is regulated by the hormone: Erythropoetin The average lifespan of a red blood cell is: 120 days/ 4 months The function of hemoglobin is to: Carry oxygen Aged and damaged erythrocytes are broken down by macrophages in the: Bone marrow, liver and spleen The important effect on RBCs functions due to their unusual shape is: Enables RBCs to for stacks, gives each RBC a large surface area to volume ration, and enable RBCs to bend and flex when entering small capillaries Red blood cells are called: Erythrocytes A persons blood type is determined by the: Presence or absece of specific antigens on the cell membrane Individuals with type A blood have: B aggulinins in their plasma Agglutinogens are contained in the _____ while the agglutinins are found in the _____: Cell membrane of RBC, plasma The blood of a person with type O blood: Contains anti-A and anti-B agglutinins Rh-negative blood indicates: Absence of the Rh antigen A type O person can donate blood to a type A person because: A type O person does not have any antigens to be attacked by the type A blood When blood types are incompatible, the blood will: Clump, agglutinate The two types of agranular leukocytes found in the blood are: Monocytes and lymphocytes Based on their staining characteristics, the types of granular leukocytes found in the blood are: Neutrophils, eosinphils, and basophils The number of eosinphils increases dramatically during: An allerigc reaction or parasitic infection The type of leukocyte responsible for the red, swollen confition in inflamed tissue is the: Basophil The multilobed white blood cell that typically fights bacteria is the: Neutrophil The leukocyte that fuses with another of its kind to create a giant phagocytic cell is the: Monocyte The most numerous WBCs in a normal WBC differential are the: Neutrophils WBCs that release histamine at the site of an injury are: Basophil WBCs other than lymphocytes are regulated by hormones called: CSF (colony-stimulation factors) In adults, the production of B&T lymphocytes is regulated primarily by exposure to antigens suchs as: Toxins, cells, and forein proteins The WBCs that are important in producing antibodies are the: Lymphocytes The normal number of WBCs in a healthy person is _____/mm3: 6000-9000 Platelets are formed elements in human blood that visually appear as: Cell fragments Platelets are responsible for: Iniating the clotting process Platelet production is called: Thrombocytopoiesis The average concentration of platelets in each microliter of circulating blood is: 350,000/ul Basophils are specialized WBCs that: Contain histamine that exaggerates the inflammatory response at the injury site Hemostaiss is a process consisting of 3 overlapping phases. The correct order is: Vascular, platelet, and coagulation phases The extrinsic pathway in blood clotting involves the release of: Tissue factor by damaged endothelial cells The "common pathway" in blood clotting involves the following events, in correct sequential order: Prothrombin- thrombin- fibrinogen- fibrin During the clotting process platelets function in: Transporting chemicals, contraction after clot formation, initiating clotting process A blod clot attached to the blood vessel wall is called: Thrombus The process of fibrinolysis: Dissolves clots The vitamin needed for the formation of clotting factors is: Vitamin K A drifting blood clot is: Embolus A clotting protein found in the bloodstream and made by the liver is: Fibrinogen
