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.
What else can I help you with?
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
Where in the kidney does secretion takes place?
Secretion takes place in the renal tubules of the kidney. Specifically, it occurs in the proximal convoluted tubule, distal convoluted tubule, and collecting ducts. These structures are responsible for selectively moving substances like drugs, ions, and waste products from the blood into the urine for excretion.
Where does selective reabsorption of glucose takes place in the nephron?
Selective reabsorption of glucose occurs in the proximal convoluted tubule of the nephron. Glucose is filtered out of the blood in the glomerulus, and then reabsorbed back into the blood through the walls of the proximal convoluted tubule.
Where does tubular reabsorbtio take plae?
Tubular reabsorption takes place in the renal tubules of the kidney, specifically in the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting ducts. This process involves the reabsorption of filtered substances such as water, ions, and nutrients back into the bloodstream to maintain homeostasis.
What is occurs in the pct?
In the proximal convoluted tubule (PCT), reabsorption of important substances such as glucose, amino acids, sodium, and water takes place. This helps maintain the body's electrolyte balance and overall fluid volume. Additionally, waste products and toxins are actively secreted into the tubule for eventual removal in the urine.
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 does active transport occur in the excretory system?
Active transport occurs in the nephron of the excretory system, particularly in the proximal convoluted tubule and the distal convoluted tubule. This process involves the movement of solutes against their concentration gradient using energy derived from ATP.
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 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.
Major components of a nephron include?
renal corpuscle and renal tubule
