What is Plasma in Blood?

Plasma is the liquid portion of blood. About 55% of our blood is plasma, and the remaining 45% are red blood cells, white blood cells and platelets that are suspended in the plasma.

• Plasma is about 92% water. It also contains 7% vital proteins such as albumin, gamma globulin and anti-hemophilic factor, and 1% mineral salts, sugars, fats, hormones and vitamins. Plasma serves four important functions in our bodies:
• 1. Helps maintain blood pressure and volume.
• 2. Supply critical proteins for blood clotting and immunity.
• 3. Carries electrolytes such as sodium and potassium to our muscles.
• 4. Helps to maintain a proper pH balance in the body, which supports cell function.
