The macula densa, composed mostly of these structures, controls the GFR. These structures, which come in juxtamedullary and cortical forms, contain a long narrow region which is permeable to sodium ions but not water, called the ascending limb. The renin-angiotensin system is regulated by these structures, which are affected by antidiuretic hormone. Bowman's capsule in these structures surrounds the glomerulus, and they have a countercurrent exchange mechanism to osmoregulate through the Loop of Henle. They are vital fo
