Glomerular oncotic pressure increases from the afferent to the efferent arteriole ends because as blood is filtered through the glomerulus, the concentration of proteins in the blood increases (since proteins are generally too large to be filtered). This increase in protein concentration raises the oncotic pressure, which is a form of osmotic pressure exerted by proteins.
