Albumin plays a crucial role in the blood plasma by maintaining oncotic pressure and facilitating the transport of various substances. Oncotic pressure is the form of osmotic pressure exerted by proteins, primarily albumin, within the blood vessels, helping to retain fluid in the circulation and prevent excessive leakage into the interstitial tissues. This is vital in maintaining blood volume and pressure.

Additionally, albumin serves as a carrier protein for various molecules, including hormones, fatty acids, and certain drugs. By binding to these substances, albumin helps to regulate their levels in the blood and allows for their transport to different tissues and organs around the body. This dual function—supporting oncotic pressure and transporting substances—highlights the importance of albumin in maintaining overall homeostasis in the body.
