Summary
This document provides an overview of blood plasma, describing its composition, which is mostly water and proteins. It explains the role of plasma proteins in maintaining blood osmotic pressure, which is essential for fluid balance in the body. The document also mentions other solutes present in plasma, such as waste products, nutrients, vitamins, hormones, gases, and electrolytes.

Blood plasma When the formed elements are removed from blood, a straw-colored liquid called plasma is left. Plasma is about 91.5% water and 8.5% solutes, most of which by weight (7%) are proteins.. Some of the proteins in plasma are also found elsewhere in the body, but those confined to blood are called plasma proteins. These proteins play a role in maintaining proper blood osmotic pressure, which is important in total body fluid balance. Most plasma proteins are synthesized by the liver, Hematology 3 including the albumins (54% of plasma proteins), globulins (38%), and fibrinogen (7%). Other solutes in plasma include waste products, such as urea, uric acid, creatinine, ammonia, and bilirubin; nutrients; vitamins; regulatory substances such as enzymes and hormones; gasses; and electrolytes.
