Question

Quizplus · Accepted Answer

Albumin is a protein that acts as a buffer in the blood, helping to maintain the pH balance by binding with both acids and bases. It is one of the most important buffers in the blood, keeping the pH within a narrow and stable range. Hemoglobin and electrolytes also contribute to the acid-base balance but to a lesser extent compared to albumin. Structural and antibody have no role in the acid-base balance of the blood.
