Which statement about albumin is true?

Which statement about albumin is true?

• A. It helps maintain osmotic pressure
• B. It is produced in the pancreas
• C. It stores bile
• D. It is the only carrier protein in blood

Answer: (A)

Albumin’s primary job in the blood is to maintain colloid (oncotic) pressure, which helps keep fluid inside the vessels and prevents excess leakage into surrounding tissues. This makes it the true statement: it helps maintain osmotic pressure. Albumin is made by the liver, not the pancreas. Bile is produced by the liver and stored in the gallbladder, not stored by albumin. And while albumin carries many compounds, it is not the only carrier protein in blood; other transport proteins and lipoproteins also help shuttle substances.
