Study Notes
- Plasma is the liquid component of blood, lacking erythrocytes, leukocytes, and thrombocytes (red blood cells, white blood cells, and platelets).
- Plasma facilitates substance movement, moderates pH, aids in infection-fighting, and assists blood clotting.
Blood Components
- Blood consists of red blood cells, white blood cells, platelets, and plasma.
- Platelets, white blood cells, and red blood cells make up 45% of blood.
- Plasma accounts for 55% of blood volume.
- Red blood cells contain hemoglobin and transport oxygen.
- White blood cells (T cells and B cells) fight disease and infection.
- Platelets are cell fragments that enable blood clotting.
- Plasma is a yellowish liquid containing proteins and electrolytes, lacking blood cells.
Plasma Composition
- Water makes up 92% of plasma.
- Clotting factors, like fibrinogen, aid in blood clotting.
- Albumin and globulin proteins maintain osmotic pressure.
- Electrolytes (potassium, sodium, bicarbonate, chloride, calcium) maintain blood's pH balance of 7.35 to 7.45.
- Immunoglobulins (antibodies) combat infections.
- Bilirubin (from hemoglobin breakdown) and carotenoids contribute to plasma's yellow color.
Function of Plasma
- Maintains osmotic pressure and blood pH.
- Transports hormones from endocrine organs.
- Transports oxygen-carrying red blood cells.
- Collects waste from cells for kidney excretion.
- Moves platelets for clotting.
- Transports white blood cells and immunoglobulins for immunity.
- Directs nutrients to cells.
- Acts as a liquid medium for blood's cellular components.
Plasma Location and Volume
- Plasma is located intravascularly (in blood vessels).
- Plasma is 91-92% water and 8-9% solids.
- The blood-to-plasma ratio is 1.02 in healthy individuals.
- Adults have roughly 0.6 to 0.8 gallons of plasma on average.
- Plasma volume can fluctuate due to hydration levels.
- Plasma is created by hydrating the body and the liver forms proteins such as bilirubin.
Importance of Plasma Donations
- Donated plasma replenishes fluids, proteins, immunoglobulins, and bilirubin.
- Medical uses include treatment for trauma, shock, liver disease, and clotting factor deficiencies.
- It takes about 48 hours for plasma to replenish.
- Plasma donation is allowed twice every 7 days with a day in between.
- Type AB+ is the universal donor for plasma.
- Type O- is a universal recipient for plasma.
- Type AB+ plasma lacks A or B antibodies, making it safe for transfusion into any blood type.
