Study Notes

Plasma Composition

  • 100 cc of plasma contains 7-8 gm of plasma proteins
  • Albumin: 4.5 gm
  • Globulins: 2.7 gm
  • Fibrinogen: 0.4 gm

Plasma Protein Synthesis

  • Albumin and fibrinogen are produced by the liver
  • Globulins are produced in the liver, spleen, bone marrow, and lymph glands

Plasma Protein Functions

  • Maintenance of Colloidal Osmotic Pressure:
    • Achieved primarily by albumin
    • Approximately 25-30 mmHg
    • Important for water exchange between blood and tissues, regulating blood volume
  • Defense Function:
    • Antibodies (primarily gamma-globulins) play a crucial role in fighting viruses and bacteria, protecting the body
  • Clot Formation:
    • Fibrinogen is essential for blood clot formation
  • Viscosity:
    • Plasma proteins, especially fibrinogen, contribute to blood viscosity, which is vital for maintaining arterial blood pressure
  • Carriers:
    • Plasma proteins transport hormones (e.g., thyroid, gonadal hormones), metal ions, fatty acids, and drugs.
