TermDefinition
Leukocytes (White cells) Primary function is to fight against infection
Erythrocytes (Red cells) Primary function is to carry oxygen to the cells and to carry carbon dioxide away from the cells
Eosinophils Stain red; Increase in number in an allergic reaction
Basophils Stain blue; Contain heparin and histamine to reduce blood clots and involvement in allergic reactions
Neutrophils Neutral; These cells are called phagocytes and ingest or destroy bacteria
Agranulocytes Cells with no granules. Includes lymphocytes, monocytes, Platelets and thrombocytes
Type A Blood Cells Recognizes itself by type A antigens, will attack any type B antigens that show up
Type B Blood Cells Recognizes itself by type B antigens, will attack any type A antigens that show up
Type AB Blood Cells Recognizes itself by both type A and B antigens, does not have any antibodies. Universal Recipient
Type O Blood Cells Does not have type A or B antigens to recognize itself. Universal Donor
Anemia Reduction in erythrocytes or hemoglobin in the blood
Polycythemia vera Opposite of anemia; There is an increase in the number of red cells which results in too many blood cells and the blood gets too thick
Hemophilia A reduction in the plasma clotting factor, resulting in a longer bleeding time
Mononucleosis An increase in the number of lymphocytes caused by the Epstein Barr virus. Known as the "kissing disease"
Multiple myeloma A malignant tumor of the bone marrow
Bleeding time Time taken for blood to stop flowing from puncture wound
Complete blood count (CBC) Measures the number of blood cells, hemoglobin, hematocrit and red cell values
Erythrocyte Sedimentation Rate (ESR) Time it takes erythrocytes to settle out of plasma; rate increases with infections
Hematocrit (Hct) Percent of erythrocytes in volume of blood
Hemoglobin (Hgb) Total amount of hemoglobin in the blood
Prothrombin time (PT) & Partial thromboplastin time (PTT) Tests the ability of the blood to clot
RBC Red Blood Count
WBC White Blood Count
BP Blood Pressure
DVT Deep Vein Thrombosis
Arteries Large elastic vessels which lead directly from the heart carrying oxygen rich blood
Arterioles Smaller vessels branched off of arteries
Capillaries Even smaller vessels that branch off of arterioles
Capillary Walls Site of gas exchange; Oxygen and nutrients leave the blood and go into the cells and waste products, such as carbon dioxide, leave the cells and go into the blood
Venules After gas exchange, blood travels back to the heart through slightly larger vessels of capillaries
Veins; Vena Cava After traveling through venules, de-oxygenated blood travels through larger vessel called ____ to the ___ and then back to the heart
Systemic Circulation Transports blood throughout the body except for the lungs
Pulmonary Circulation Transports blood to the lungs and back to the heart
Mediastinum Area in the chest between the two lungs
Endocardium Smooth inside lining that keeps blood flow unobstructed
Myocardium Responsible for pumping the blood through and out of the heart
Pericardium Fluid filled bag around the heart which acts as a shock absorber and makes sure that the heart can move unobstructed
Atria Top two chambers in the heart, left & right
Ventricles Bottom two chambers in the heart, left & right
