Which nephron is also known as long loop nephron?

Which nephron is also known as long loop nephron?

loop of Henle, long U-shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles, birds, and mammals.

What is the name for the repeating functional unit of the kidney?

The functional unit of the kidney is called the nephron. It comprises of a coiled renal tubule and a vascular network of peritubular capillaries.

Which of the following is a function of the urinary system *?

The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The kidneys make urine by filtering wastes and extra water from blood.

Why is the loop of Henle important in osmoregulation?

The loop of Henle acts as a countercurrent multiplier that uses energy to create concentration gradients. The descending limb is water permeable. Water flows from the filtrate to the interstitial fluid, so osmolality inside the limb increases as it descends into the renal medulla.

How do Juxtamedullary nephrons concentrate urine?

The nephron loop of juxtamedullary nephrons is the apparatus that allows the nephron to concentrate urine. The loop is a countercurrent multiplier system in which fluids move in opposite directions through side‐by‐side, semi‐permeable tubes.

Which nephrons are better at concentrating urine?

Although both cortical and juxtamedullary nephrons regulate the concentrations of solutes and water in the blood, countercurrent multiplication in the loops of Henle of juxtamedullary nephrons is largely responsible for developing the osmotic gradients that are needed to concentrate urine.

Which of the following is a function of the nephron loop?

This part of the nephron is called the loop of Henle. Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.

Which of the following is the primary function of the Juxtaglomerular complex?

Which of the following is the primary function of the juxtaglomerular complex? releases chemical signals that regulate the rate of filtrate formation; The macula densa cells and granular cells of the juxtaglomerular complex (JGC) release, respectively, vasoactive chemicals and renin.

Where are Juxtamedullary nephrons located?

Juxtamedullary nephrons are found only in birds and mammals, and have a specific location: medullary refers to the renal medulla, while juxta (Latin: near) refers to the relative position of the renal corpuscle of this nephron – near the medulla, but still in the cortex.

What function is unique to the nephron loop quizlet?

create a gradient for urine concentration and water conservation.

What is the importance of having a long loop of Henle and short loop of Henle in a nephron?

The counter-current system of the Loop of Henle is involved in the recovery of the water and NaCl from urine. The longer the Loop of Henle, the higher the osmolarity of the fluid as it contains more water. The short loops of the cortical nephrons passively reabsorb urea in the thick ascending limbs.

What is the relationship between the length of the loop of Henle and the type of urine produced?

Solution : There is a correlation between the length of loop of Henle and the concentration of the urine produced. The longer, the length of Henle’s loop, the greater, the concentration gradient and more concentrated the urine will be.
