Study Notes
What is Blood Plasma?
- Blood plasma is the liquid component of blood remaining after removing blood cells (erythrocytes, leukocytes, and thrombocytes).
- Plasma is crucial for transporting substances, regulating pH, fighting infections, and assisting in blood clotting.
Components of Blood Plasma
- Water is the primary component of plasma, making up 91-92%.
- Other components include clotting factors (e.g., fibrinogen), proteins (albumin, globulin), electrolytes (potassium, sodium, bicarbonate, chloride, calcium), and immunoglobulins.
- The presence of bilirubin and carotenoids gives plasma its yellowish color.
Functions of Blood Plasma
- Plasma transports hormones, oxygen-carrying red blood cells, waste products, platelets, white blood cells, nutrients, and acts as a suspending medium for blood cells.
- Plasma helps maintain osmotic pressure and regulates blood pH (7.35-7.45).
Plasma in the Human Body
- Plasma is found inside blood vessels (veins and arteries), referred to as intravascularly.
- The blood-to-plasma ratio in healthy individuals is 1.02 (45% blood, 55% plasma).
- The average adult has around 0.6-0.8 gallons of plasma, but this can fluctuate due to dehydration or excessive water intake.
Importance of Plasma
- Donated plasma replenishes missing fluid, proteins, immunoglobulins, and bilirubin in patients.
- Plasma is used in transfusions for trauma and shock patients, treatment of liver disease, and clotting factor deficiencies.
- It is also used in clinical and laboratory research.
- Plasma replenishes in approximately 48 hours, allowing donations twice every 7 days with a day between donations.
Plasma Donation
- Plasma donation is opposite to blood type matching.
- Type O- blood is a universal donor for blood transfusions but a universal recipient for plasma donation.
- Type AB+ plasma, which lacks A or B antibodies, is a universal donor for plasma transfusions.
