What is the function of the ascending limb of the loop of henle?
The function of the ascending loop of henle is draw Sodium out of the filtrate. The ability of the ascending loop to actively transport sodium into the surrounding tissue is directly related to the amount of water that can be diffused out of the descending loop of henle. (main factor in water re-absorption)
Is there anything that solids can pass through but liquids cant?
Yes, the ascending limb of the loop of Henle.
What are the main functions of the Loop of Henle in urine formation?
absorption of water (from descending limb), absorption of Na+ (from ascending limb)
What is the primary function of the ascending loop of henle?
the primary function of the ascending loop of henle in the kidney
The Segment of the nephron that is not permeable to water even in the presence of vasopressin is called what?
The Ascending limb of the loop of Henle
How would hypertonic urine be produced from an isotonic blood plasma?
# Water is reabsorbed all along the nephron. # Urine becomes hypertonic (salty) because of the loop of Henle and the collecting duct. # Loop of Henle # The descending limb of the loop of Henle can't absorb salt, and the ascending limb can't absorb water. # Salt passively diffuses out of the lower portion of the ascending limb. # The upper part of ascending limb actively transports salt into tissue of the renal medulla. # Increase in salt in the direction of the inner medulla. # Urea leaks from the lower portion of collecting duct and contributes to a high solute (salt) concentration. # Water leaves descending limb of the loop of Henle, returning to the blood. # Urine is hypertonic to blood.
What has the author Sally Rachel Jacobs written?
Sally Rachel Jacobs has written: 'Magnesium reabsorption in the thick ascending limb of the loop of Henle'
To maintain solute concentration gradient in the renal medulla what is required?
active transport of sodium and chloride ions from the ascending limb of the loop of Henle.
What is the process that actively moves substances from the blood into the nephron?
in the ascending limb of the loop of Henle
What is the function of descending limb of Henle hoop?
In the ascending loop, Na+ (or any solute) is actively pumped out of the tubule. As flow continues up the loop, the tubular concentration decreases as does the interstitial (the fluid surrounding the loop) concentration.Because water is impermeable in the ascending loop, the volume at the bottom of the loop is the same as that entering the distal tubule. At the bottom of the loop, the tubular and interstitial concentrations are equal.The ascending loop of Henle actively pumps sodium and potassium out but water can not follow. This concentrates the water inside the loop of Henle.
Which part of the loop of Henle contains more dilute urine?
The thick descending limb contains the most dilute filtrate (it is not called urine at this stage). It become more concentrated as it travels through the loop of Henle. It should be noted that this is not because more solute is added but instead because the water is reabsorbed into the blood along the loop of Henle. The Ascending Loop is the most dilute, because it is permeable to salts not H20, and passes through a Decreasing Salt Barrier. The thick portion of the ascending linb actively pumps Cl ions out of the tubular fluid and into the surrounding tissue. The ascending limb is impermeable to water, however, and so water does not follow the sodium and Cholride by osmmosis. The result is that the tublar fluid becomes more and more dilute as it flows up the ascending limb.
The thick segments in the ascending limb of the loop of Henle contain A ADH-regulated permeability. B an aldosterone-regulated pump. C transport mechanisms that pump solutes out of the filtra?
a
