What Are the Components of Blood Plasma?

Human blood is made up of a few key components. Plasma is the liquid component of blood, and the red blood cells, white blood cells and platelets are suspended within it.

Features

Plasma accounts for more than half of the blood's volume. According to merck.com, plasma consists of mostly water which holds electrolytes and protein.

Albumin

The most important protein in plasma is albumin. Albumin keeps fluid from leaking out of blood vessels and into tissue. Albumin also carries certain hormones and drugs.

Antibodies

Plasma also contains other proteins such as immunoglobulins, which are commonly referred as antibodies. Antibodies defend against viruses, bacteria, fungi and cancer cells.

Function

The components that make up plasma help to either replenish insufficient water from tissue or absorb excess water. According to merck.com, plasma also prevents blood vessels from collapsing and clogging.

Significance

The components that form plasma play one of the most important roles in the body. Plasma is essential to fighting off diseases and regulating the inner workings of the human body.
