Albumin is a small protein, which makes up more than half of the total serum protein content of the blood. It is produced in the liver. The diffusion of albumin from the serum does not occur freely. Therefore, albumin is critical in providing colloid osmotic or oncotic pressure, which is important in the regulation of the movement of water and solutes across the capillary walls.
