What is the role of albumin in the body?

Albumin plays a crucial role in maintaining oncotic pressure, which is essential for the regulation of fluid balance between blood vessels and surrounding tissues. This protein, produced in the liver, helps to keep water within the blood vessels, preventing excessive fluid leakage into the tissues, which can lead to edema.

In addition, albumin serves as a transport protein for various substances, including hormones, fatty acids, and drugs. Its ability to bind to these molecules facilitates their transport through the bloodstream, making them available for physiological processes throughout the body. The dual function of maintaining oncotic pressure and acting as a carrier for numerous substances underscores the importance of albumin in maintaining overall homeostasis in the circulatory system.
