Plasma

Plasma is an aqueous solution of a number of different organic solutes, and is one of the basic components of blood.

Composition

In addition to water, plasma contains plasma proteins, Na⁺, K⁺, Ca²⁺, Mg²⁺, Cl^-, HCO₃^-, H₂PO₄^-/HPO₄^2- and glucose ^[1]. The proteins include albumin and fibrinogen^[2], along with numerous other clotting factors.

The composition of plasma is very similar to that of interstitial fluid, except that interstitial fluid contains no plasma proteins.
