When systemic blood pressure increases, how does the kidney respond to maintain glomerular fi ltration rate? A. The afferent arteriole dilates B. The efferent arteriole constricts C. The efferent arteriole dilates D. The afferent arteriole constricts
Option D. An increase in BP stretches the walls of the efferent arteriole which respond through constricting. The resulting lower in diameter decreases glomerular blood flow which maintains Glomerulus filteration rate inside regular limits.
