which is most responsible for the formation of concentrated urine course hero

Which is most responsible for the formation of concentrated urine?

Explanation: The special arrangement of Henle's loop and vasa recta and counter-current mechanism helps in maintaining and increasing the osmolarity towards the inner medullary interstitium in the kidneys. This interstitial gradient helps in concentrating the urine.

What organ is responsible for concentrating urine?

The region of the kidney that is responsible for the generation of concentrated or dilute urine is the medulla (Figure 1).

Which nephron type is responsible for making concentrated urine?

loop of juxtamedullary nephronsThe nephron loop of juxtamedullary nephrons is the apparatus that allows the nephron to concentrate urine.

Where is urine most concentrated?

The region of the kidney that is responsible for the generation of concentrated or dilute urine is the medulla (figure 1).

Which part is responsible for concentrating the solute in the filtrate?

Reabsorption in the loop of Henle: The filtrate then enters the loop of Henle (descending and ascending limbs), which is responsible for concentrating or diluting the tubular fluid using a process called countercurrent multiplication.

Do cortical nephrons concentrate urine?

Cortical nephrons (85% of all nephrons) mainly perform excretory and regulatory functions, while juxtamedullary nephrons (15% of nephrons) concentrate and dilute urine.

Which part of nephron is called concentrating segment?

The collecting ducts constitute the concentrating segment of the nephron.

How concentrated urine is formed?

Urine is concentrated in the final stages of its production: water is absorbed, in excess of solute, from the collecting ducts and into the vasculature of the medulla, thus increasing the osmolality of the collecting duct fluid and thus the osmolality of the urine that emerges from the collecting ducts.

Does ADH make urine more concentrated?

ADH normally causes the kidneys to make the urine more concentrated. As a result of not responding to the ADH signal, the kidneys release too much water into the urine.

What does ADH do to urine concentration?

Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine. A low level results in greater urine production.

What does urine concentration mean?

‌A urine concentration test provides the specific gravity of your urine. This measures your kidneys' ability to balance water content and excrete waste. It is important in diagnosing some health conditions that impact water content in your urine.
