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.
