    • Process in which platelets clump or aggregate together to form a plug or clot
 
agglutination
    • Substance that inhibits blood clot formation
 
    • anticoagulant
    • Formation of blood clot
 
    • coagulation
    • diluting agent
 
    • diluent
    • Abnormal blood or bone marrow condition, such as leukemia
 
    • dyscrasia
    • Red blood cells; contain hemoglobin, which carries oxygen from the lungs to the body’s cells
 
    • erythrocytes
    • The study of blood
 
    • hematology
    • Process by which the body spontaneously stops bleeding and maintains the blood in a fluid state within the vascular compartment
 
    • hemostasis
    • The study of antigens, antibodies, and their interactions
 
    • immunohematology
    • White Blood Cells; different types of cells that protect against bacterial infection and other foreign invaders
 
    • leukocytes
    • Having the ability to ingest particulate material, such as bacteria
 
    • phagocytic
    • Individual trained to draw blood
 
    • phlebotomist
    • Process of blood collection, sometimes defined as “an incision into a vein”
 
    • phlebotomy
    • Liquid portion of anticoagulated blood
 
    • plasma
    • Liquid portion that remains when the blood has been allowed to clot
 
    • serum
    • Measurement or estimate of the amount of color in a solution
 
    • spectrophotometric
    • Platelets; smallest cells found in blood
 
    • thrombocytes
    • Method of obtaining venous blood for analysis of hematology and chemistry studies
 
    • venipuncture
Components of Blood
 
    • Plasma: 50-55 percent of blood content
    • Cellular components:
      • Erythrocytes: 45-50 percent of blood volume
      • Leukocytes and thrombocytes (buffy coat) less than 1%
  • Liquid portion of uncoagulated blood
  • Mostly water: 90 percent
  • Also made of
    • Sugars, salts, gases, hormones
    • Antibodies, minerals, vitamins, coagulation factors, and waste products
 
    • Plasma
    • most common WBC and defend body against infection, especially bacterial
 
    • Neutrophils
    • second most WBC, common in adults and first in children; aid immune defense against viruses
 
    • Lymphocytes
    • Largest WBC cells; play role in cell-mediated immunity (Viruses)
 
    • Monocytes
    • WBC cells that function in allergic or inflammatory responses
 
    • Eosinophils
    • least number of WBC cells and react in allergic states
 
    • Basophils
  • Smallest cells found in blood
  • Critical for coagulation and forming blood clots to stop bleeding
  • Low platelet count means blood will not coagulate easily
 
    • Platelets
