Blood Plasma Composition
Captions available
The idea
Plasma, blood's liquid matrix, is mostly water and carries dissolved proteins, nutrients, hormones, gases, and waste products between organs.
In practice
Albumin, a major plasma protein, helps maintain the osmotic pressure that keeps water from leaking excessively out of blood vessels.
Where people slip
Plasma is not merely a passive carrier fluid — several of its dissolved proteins perform active regulatory roles of their own.
