Verified step by step guidance

Step 1: Understand the role of albumin in blood plasma. Albumin is a protein produced by the liver and is the most abundant plasma protein in the blood.

Step 2: Learn about osmotic pressure. Albumin helps maintain osmotic pressure by regulating the balance of water between blood vessels and surrounding tissues. This prevents excessive fluid loss from the blood into tissues.

Step 3: Explore albumin's role in substance transport. Albumin binds to and transports various substances, such as hormones, fatty acids, and drugs, through the bloodstream.

Step 4: Eliminate incorrect options. Albumin is not responsible for blood clotting (this is the role of fibrinogen), is not an antibody (immunoglobulins are antibodies), and does not act as a hormone regulating red blood cell production (this is the role of erythropoietin).

Step 5: Conclude that the correct function of albumin is to help maintain osmotic pressure and transport substances in the blood.
