Explanation:
Detailed explanation-1: -The first is the myogenic response of preglomerular arterioles. Elevations in transmural pressure induce contraction of preglomerular arterioles, predominantly at the level of afferent arterioles. The other mechanism is tubuloglomerular feedback which acts in concert with the myogenic response.
Detailed explanation-2: -Blood enters the kidneys through an artery from the heart. Blood is cleaned by passing through millions of tiny blood filters. Waste material passes through the ureter and is stored in the bladder as urine. Newly cleaned blood returns to the bloodstream by way of veins. More items
