  • Erythrocytes
    The most numerous cells in blood, responsible for oxygen and carbon dioxide transport, giving blood its red color.
  • Leukocytes
    White blood cells found in the buffy coat, crucial for immune response and fighting infections.
  • Thrombocytes
    Cell fragments in the buffy coat, essential for blood clotting and reducing blood loss after injury.
  • Plasma
    The liquid extracellular matrix of blood, comprising 90% water, electrolytes, and proteins, making up 55% of blood volume.
  • Hematocrit
    The percentage of blood volume composed of red blood cells, indicating overall health, typically 36-50%.
  • Cardiovascular System
    Comprises the heart, blood, and blood vessels, responsible for circulating blood throughout the body.
  • Connective Tissue
    A type of tissue in the body, with blood being the only liquid form, involved in support and transport functions.
  • pH
    A measure of acidity or alkalinity, with blood being slightly alkaline, ranging from 7.35 to 7.45.
  • Buffy Coat
    A thin layer in blood containing leukocytes and thrombocytes, making up less than 1% of blood volume.
  • Albumin
    A protein in plasma that helps maintain fluid balance and transport substances in the blood.
  • Globulins
    Proteins in plasma involved in immune functions and transport of lipids and fat-soluble vitamins.
  • Fibrinogen
    A plasma protein essential for blood clot formation, converting to fibrin during the clotting process.
  • Extracellular Matrix
    The nonliving component of blood, primarily plasma, providing a medium for cellular components.
  • Vasoconstriction
    The narrowing of blood vessels to reduce blood flow and heat loss, aiding in temperature regulation.
  • Vasodilation
    The widening of blood vessels to increase blood flow and heat loss, aiding in cooling the body.
