Human plasma
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid.
Plasma serves four important functions in our body:
- Helps maintain blood pressure and volume.
- Supply critical proteins for blood clotting and immunity.
- Carries electrolytes such as sodium and potassium to our muscles.
- Helps to maintain a proper pH balance in the body, which supports cell function.
