Glomerular filtration is the renal process in which the fluid in the blood is filtered into the Bowman's capsule across the glomerulus capillaries. This filtration occurs due to the force of the difference between hydrostatic and osmotic pressure. Afferent and efferent arterioles transport blood in and out of the glomerulus. The afferent arteriole which brings in the blood is large in diameter which helps in increased blood pressure in the glomerulus. Hence, statements I II are correct.
