In the embryo, these structures develop when a Wnt4-induced vesicle elongates into a comma-shaped body, followed by an S-shaped stage. One section of these structures produces the Tamm-Horsfall glycoprotein. People with interuterine growth restriction have fewer of these at birth and a higher chance of hypertension later in life. Barter and Gitelman's syndromes are caused by mutations in proteins found here. Mutations in PKD1 cause cysts to appear throughout these structures.

NKCC2 localizes to one part of this structure, which is acted upon by furosemide. One section of this structure that feeds back onto a previous section is the (*) macula densa, and peritubular capillaries surround it. One section of this structure dips into the medulla, uses a countercurrent multiplier mechanism, and is surrounded by the vasa recta. Ultrafiltration occurs in its vascular pole, which forces filtrate into Bowman's capsule. For 10 points, name these structures which contain the glomerulus and Loop of Henle, the functional unit of the kidney.

nephron [prompt on “kidney”, anti-prompt on more specific parts of the nephron like glomerulus, Bowman’s capsule, proximal convoluted tubule, Loop of Henle, etc]
