    Study Notes

    Introduction to Hematology

    • Hematology derives from Greek, combining "haima" (blood) and "logos" (study).
    • Blood is a red liquid circulating through the heart, veins, arteries, and capillaries.

    Types of Blood Vessels

    • Arteries:

      • Distributing blood vessels exiting the heart with thickest walls.
      • Diameter: approximately 4 mm.
    • Veins:

      • Collecting blood vessels returning to the heart, largest vessels with an irregular lumen.
      • Diameter: approximately 5 mm.
    • Capillaries:

      • Smallest blood vessels facilitating exchange between arterial and venous systems.
      • Diameter: approximately 8 micrometers (um).

    Functions of Blood

    • Respiratory: Transports oxygen and carbon dioxide.
    • Nutritional: Provides nutrients to cells.
    • Excretory: Eliminates waste products.
    • Buffers body pH and maintains temperature.
    • Carries hormones and contributes to defense mechanisms.

    Blood Composition

    • Liquid Portion:
      • Plasma: Unclotted blood component.
      • Serum: Liquid portion after clotting.
    • Solid Portion:
      • Red Blood Cells (RBCs): Erythrocytes; also known as erythroplastids or akaryocyte (nucleus-free cells).
      • White Blood Cells (WBCs): Leukocytes; categorized as granular (Basophils, Eosinophils, Neutrophils) and agranular (Lymphocytes, Monocytes).
      • Platelets: Thrombocytes involved in clotting.
    • Gaseous Portion: Includes oxygen and carbon dioxide.

    Blood Collection

    • Patient Identification:

      • Confirm patient’s full name, age, gender, and birthdate; should be done by the patient.
      • Critical step; mislabeling is a significant error.
    • Phlebotomist Hygiene:

      • Essential for maintaining health and hygiene: clean clothes, hair, and short fingernails.
      • Adhere to standard precautions, especially with gloves and handwashing.

    Characteristics of Blood

    • Fluid state (in vivo).
    • Slightly alkaline pH.
    • Average specific gravity: 1.055.
