if you think about it, the role of the loop of henle is to essentially get as high a concentration of salts in the collecting duct as possible to get concentrated urine because it's trying to get as much water water as possible reabsorbed back into the body.
now that we know this we can pretty much work from there. after the fluid has moved through the descending limb (which is water permeable meaning that it loses water through osmosis to the tissue fluid in the medulla) and the ascending limb (which is water impermeable meaning the opposite), the fluid is very high in concentration of salts because salts keep moving into the tubule after the top of the descenting limb.
therefore, by the time the fluid gets to the distal convoluted tubule, the urine is low in water potential already. sodium ions move out of the fluid and potassium ions move into the tubule. water also continues to diffuse out of the tubule and also later on in the collecting duct. depending on how hydrated the body is, more and more water is reabsorbed back into the tissue fluid in the medulla before being absorbed by the capillaries and carried away by the blood. this is all done to prevent dehydration.

Does condensation takes place all the time?
Condensation takes place at any temperature. Condensation takes place at any temperature.
Oogenesis takes place in the what?
In most animals it takes place in the female gonads, the ovaries.
How does rain take place?
Relief rainfall takes place when evaporation,transpiration and condensation takes place followed byprecipitation
Do you always feel when implantation takes place?
As far as I am aware you don't feel when implantation takes place.
Where does an inference take place?
An inference takes place in an observation
Where does selective reabsorption takes place?
The proximal convoluted tubule
Most electrolyte reabsorption by the renal tubes?
Tubular reabsorption takes place in the kidneys. It specifically occurs in nephrons, microscopic tubular structures (Proximal Convoluted Tubule-PRIMARY & Distal Convoluted tubule-SECONDARY) of the kidney that number in the millions.
Where does glucose reabsorption occur in the nephron?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
Nephron tube where nutrients are reabsorbed?
The Nephron is the functional unit of the Kidney which regulates blood contents NOT urine contents. It works by filtering out much of the contents of the blood from the Glomerulus into Bowmans Capsule. From here the a long tubule projects and is followed by a blood vessel (the Efferent Capillary) which reabsorbs much of the nutriens, what isn't reabsorbed goes into the Urine via a Collecting Duct. There are three parts to the nephron, the Proximal Convoluted Tubule, the Loop of Henle and the Distal Convoluted Tubule. The loop of Henle is mostly involved in the reabsorbtion of water with the use of salts. The majority of nutrients reabsorbtion takes place is the proximal convoluted tubule. It should be noted that although the nephron is very efficient (it reabsorbs 90% of the water if need be) it also reabsorbs about 50% of the urea so it is incorrect to think that it all goes straight into the urine. In short, to answer you question, most nutrients are reabsorbed in the Proximal Convoluted Tubule.
Where in the kidneys does the filtering takes place?
Within the nephron (the functional unit of the kidneys), filtration occurs in the glomerolus. The filtered fluid is called filtrate. Reabsorption of filtrate occurs in a few places within the nephron, however, the majority of reabsorption takes place in the proximal convoluted tube. It is important to mention that additional reabsorption occurs in the Loop of Henle, distal convoluted tube, and the collecting ducts as well. Again, however, MOST reabsorption of filtrate from the glomerolus takes place in the proximal convoluted tube of the nephron.
Where does glucose take place?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
Where does most reabsorption occur in the kidney?
The proximal tubule is the site of most reabsorption via glucose transporters (reabsorb 100% of glucose in healthy individuals), approx. 65% Sodium and various other solutes are also reabsorbed.
Does ADH increase water absorption?
ADH is what signals the body to retain urine. The reason urine is produced heavily when you drink alcohol the ADH is blocked so you have to urinate more often. Well if ADH is present the urine that pass will be more concentrated because resorption of water takes place at distal convoluted tubule of nephron and collecting duct in the kidney. But that happens only if ADH is present.
What is the difference between the renal tubule and the renal corpuscle?
The renal corpuscle is composed of the Bowman's capsule and the glomerulus, the site of filtration. The renal tubule is composed of the proximal convoluted tubule, the loop of Henle, and the distal tubule. This is where reabsorption and secretion takes place as the filtrate is converted into urine.
Where does osmoregulation take place in the urinary system?
In the urinary system, osmoregulation takes place in the renal tubules and collecting ducts in the kidney. These parts are where selective reabsorption takes place, where water, glucose, salts and other necessary substances are absorbed back into the surrounding blood capillaries, from the renal tubule, which eventually leads to the bladder. The tubule is affected by the hormone ADH (anti-diuretic hormone) from the pituitary gland in the brain, which makes the renal tubule membrane more permeable, so more water can be reabsorbed, or vice versa - Makes the membrane more permeable so that more water is excreted. Osmoregulation is an example of homeostasis.
Major components of a nephron include?
renal corpuscle and renal tubule
What is the process of reabsorption as it occurs in nephrons?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
