Blood Flashcards
3 types of blood cells
Erythrocytes, leukocytes, thrombocytes
Major proteins found in blood
Albumin, globulin, fibrinogen
Albumin
Maintains oncotic pressure
Globulins
Major component of immune system
Fibrinogen
Used to clot blood
3 major functions of blood
Transportation, regulation, defense
Plasma
Liquid portion of WHOLE BLOOD
Serum
Liquid portion of CLOTTED BLOOD
Buffy coat
Layer of centrifuged blood that separates plasma and RBC
Four major colors of Plasma/serum
Normal (straw colored plasma/serum), hemolytic, icteric, lipemic
Hemolytic plasma
Pink or red, indicates hemolysis
Icteric
Yellow, indicates hepatic disease or severe hemolysis
Lipemic
Milky/cloudy, indicates diet high in fat
5 types of WBC/Leukocytes
Neutrophils, lymphocytes, monocytes, eosinophils, basophils
Neutrophils
Granulocytes, don’t really stain; most common WBC, active immune response- “first responders”
Lymphocytes
Agranulocyte; involved with immune system. Smallest leukocyte. 4 kinds of leukocytes: T-cells, B-Cells, plasma cells, NK (natural killer) cells
Monocytes
Agranulocytes; “second responder”, active immune response via phagocytosis. More common in chronic conditions
Eosinophils
Granulocyte, stains red/pink; anti-inflammatory response, assists with immune system
Basophils
Granulocyte, stains blue; contain histamine and heparin (for allergic response and anticoagulation). Rarest and least understood blood cell.
Hemoglobin
A proteins found in red blood cells. Gives it its red color. Iron in it binds to oxygen, also carries carbon dioxide and protons.
Petechiae
Pin-point and numerous bruises caused by thrombocytopenia
Ecchymosis
Larger abs covering more area; bruises caused by thrombocytopenia
