How does the path of the ureters through the bladder wall minimize the chances of vesicoureteric reflux (see Related Clinical Terms) and hydronephrosis (see “The Urinary System Throughout Life”)?
In a histological section of cortical kidney, renal corpuscles are surrounded by...
O proximal tubules
O proximal and distal convoluted tubules as well as thin limbs of the loops of Henle
proximal and distal convoluted tubules
O proximal tubules and loops of Henle with distal tubules forming the medullary
rays
Vesicoureteral reflux occurs in children because:
O a. as the bladder in infants and children fill, it pulls the smooth lining of the transitional epithelium
away from the ureters so that the reflux valves are ineffective.
b. the submucosal segment of the ureter is short, making the antireflux mechanism inefficient.
O c. they do not ask for help in urinating in a timely manner and urine is forced up into the ureters.
d. the trigone lying between the opening to the ureters and the urethra is underdeveloped.

Three physiological categories of suchdrugs are ones that (i) function as loop diuretics, (ii) inhibitthe action of aldosterone, and (iii) block Na+ channels in thecollecting ducts. Explain why each of these categories wouldbe expected to increase Na+ excretion and urine flow.
