Answer

Constriction of the efferent arteriole Explanation 1. Understand Filtration Pressure Filtration pressure is influenced by hydrostatic and osmotic pressures in the glomerulus. It increases when glomerular hydrostatic pressure rises or opposing pressures decrease. 2. Analyze Effects of Efferent Arteriole Constriction Constriction of the efferent arteriole increases glomerular hydrostatic pressure, enhancing filtration pressure.
