Chapter 44, Problem 4TYU
Summary Introduction
Introduction:
Renal medulla is the inner part of the kidney and it consists of a loop of Henle, collecting ducts etc. Their function is to regulate the concentration of urine. It also regulates the water and salts inside the body.

Which of the following associations is correct?
Parietal layer of glomerular Capsule – Part of the filtration membrane
Visceral layer of glomerular Capsule – Contains podocytes
Proximal convoluted tubule – Simple cuboidal epithelium with microvilli
Glomerulus – Receives blood from the afferent arteriole
Loop of Henle – Helps create the osmolarity gradient in the renal medulla
Which of the following associations is
correct? *
Parietal layer of glomerular Capsule - Part
of the filtration membrane
Proximal convoluted tubule - Simple
cuboidal epithelium with microvilli
Glomerulus - Receives blood from the
afferent arteriole
Visceral layer of glomerular Capsule -
Contains podocytes
Loop of Henle - Helps create the osmolarity
gradient in the renal medulla
The ability to reduce both volume and water concentration of urine depends on the following:
a. Countercurrent flow between the descending and ascending loop of Henleb. Countercurrent flow between the vasa recta and the loop of Henlec. High interstitial osmolarity in the medullad. Recycling of urea in the nephrone. All of the above

- Fatty tissue holds the kidneys in place. Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow.
