The descending thin loop is a primary site of water absorption. In contrast, the ascending loop is permeable to ions rather than water.

Full Answer

What is the function of loop of Henle?

Loop of Henle is a long U-shaped part of the tubule that leads urine in each nephron of the kidney of reptiles, mammals and also in birds. The main role of the loop of Henle in nephron is to collect sodium chloride and water from urine.

Why is the ascending loop of Henle function impermeable to water?

The ascending loop of Henle function is impermeable to water. In this, sodium chloride is transported from a thick portion of the ascending limb without accompanying water so an osmotic gradient of approximately 200 mosm/kg is generated.

What is the function of the thick descending limb of Henle?

The thick descending limb of the loop of Henle expresses a sodium-potassium-chloride cotransporter and helps reabsorb approximately a third of the filtered sodium and chloride from the fluid in the tubular lumen into the blood. Some of the Loops of Henle Functions are- Homeostatic mechanisms to regulate extracellular fluid volume

What are the three main segments of the loop of Henle?

Anatomically, the loop of Henle can be divided into three main segments: the thin descending limb, the thin ascending limb, and the thick ascending limb (sometimes also called the diluting segment). Each nephron of the kidney contains blood vessels and a special tubule.

1. What are the major functions of the loop of henle?

Loop of Henle is found in the kidney location and has three major functions.Re-absorption: It absorbs 15% of filtered water and 25% of the filtered...

2. What activity happens in the ascending loop of henle?

The ascending loop of Henle carries a thin and thick segment. It helps in draining urine into the distal convoluted tubule. The sodium reabsorption...

3. What is the role of the ascending loop of henle?

The ascending Loop of Henle is impermeable to water. Here, the sodium chloride is transported from a thick portion of the ascending limb without ac...

4. What are the functions of nephron?

The primary function of the Nephron is to flush out the waste products such as solid waste and other excesses from the blood. Nephron is a basic st...

5. Mention one essential part of nephron?

An essential part of Nephron is Henle’s Loop, also known as Loop of Henle. The Henle’s loop carries both the descending limbs of Loop of Henle and...

6. What is PCT?

PCT or Proximal Convoluted Tubule is an essential part of Nephron. PCT can be described as a system that helps in the absorption and the reabsorpti...

7. Where are study notes available?

Biology is an important subject and it is necessary to have clear concepts of all the chapters. Practice is important so as to be able to do well a...

8. What are the three essential parts of nephron?

Nephron carries three different parts of tubules for secretion purpose. These three are-1. Proximal Convoluted Tubule (PCT)The blood brought by the...

What are the three segments of the loop of the henle?

Anatomically, the loop of Henle can be divided into three main segments: the thin descending limb, the thin ascending limb, and the thick ascending limb (sometimes also called the diluting segment). Each nephron of the kidney contains blood vessels and a special tubule.

What is the liquid in the loop of Henle?

The liquid entering the loop of Henle is the solution of salt, urea, and other substances passed along by the proximal convoluted tubule, from which most of the dissolved components needed by the body—particularly glucose, amino acids, and sodium bicarbonate—have been reabsorbed into the blood.

What is the loop of a nephron?

Alternative Titles: Henle’s loop, nephronic loop. Loop of Henle, long U-shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles, birds, and mammals. The principal function of the loop of Henle is in the recovery of water and sodium chloride from urine.

Where does the glomerular filtrate enter the loop of Henle?

About one-third of the volume of the glomerular filtrate enters the descending limb of the loop of Henle. This fluid is isosmotic with plasma. The reabsorptive characteristics of the descending thin limb and those of the bend of the loop differ greatly…

Which segment of the loop is permeable to water?

The first segment of the loop, the thin descending limb, is permeable to water, and the liquid reaching the bend of the loop is much richer in salt and urea than the blood plasma is. As the liquid returns through the thin ascending limb, sodium chloride diffuses out of the tubule into the surrounding tissue, where its concentration is lower.

Which segment of the loop is responsible for the removal of salt?

In the third segment of the loop, the thick ascending limb, the tubule wall can, if necessary, effect further removal of salt, even against the concentration gradient, in an active-transport process requiring the expenditure of energy.

How does the filtrate of the nephron work?

As the filtrate flows through the tubule of the nephron, it becomes increasingly concentrated into urine. Waste products are transferred from the blood into the filtrate while nutrients are absorbed from the filtrate into the blood. Encyclopædia Britannica, Inc. Read More on This Topic.

29 hours ago Role of the Descending Loop of Henle. The descending limb is highly permeable to water and the reabsorption occurs via AQPI channels. During this process, low amounts of urea Na+ and other ions are reabsorbed. Functions of Nephron. The primary function of Nephron is to flush out waste products which include solid waste and other excess from the blood.

21 hours ago loop of Henle, long U-shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles, birds, and mammals. The principal function of the loop of Henle is in the recovery of water and sodium chloride from urine. This function allows production of urine that is far more concentrated than blood, limiting the amount of water needed as intake for survival.
