What two substances can be found in the glomerular filtrate?
Basically blood plasma minus proteins. The glomeruli can filter out most serum proteins, but lets a few small ones through (I think the cutoff is like 25kD). Some albumin does manage to get through, this is recovered in the proximal tubule.
What Polysaccharide substance is used to determine Glomerular Filtration Rate?
Inulin is a polysaccharide substance commonly used to determine glomerular filtration rate (GFR) as it is freely filtered by the glomerulus and neither reabsorbed nor secreted by the renal tubules. Inulin clearance is considered to be the most accurate measure of GFR.
What is glomerular absorption?
Glomerular absorption refers to the process by which substances are reabsorbed from the renal tubules back into the bloodstream after filtration occurs in the glomerulus of the kidneys. Although the term is often used to describe the reabsorption of water, electrolytes, and nutrients, it is important to note that most reabsorption occurs in the renal tubules rather than in the glomerulus itself. This mechanism is crucial for maintaining fluid and electrolyte balance in the body. Overall, glomerular absorption plays a significant role in urine formation and homeostasis.
How much of the fluid that comprises filtrate is reabsorbtion into the bloodstream?
Most filtrate is reabsorbed. Remember, just about everything other than cells and large proteins is filtered into Bowman's capusle, and your body needs most of it, or else all you would have running through your blood are cells and proteins. The kidneys reabsorb most of the water, ions and nutrients in the filtrate.
What is left in the nephrons?
In the nephrons, the filtrate from the blood is processed to reabsorb essential substances like water, glucose, and electrolytes, while removing waste products like urea. By the time the filtrate reaches the collecting duct, most of the water and necessary solutes have been reabsorbed, and what's left is predominantly waste material that will be excreted as urine.
Where does most of the fluid go after glomerular filtrtion?
Glomerular filtration is part of the process in the formation of urine. After the process of glomerular filtration is carried out, most of the fluid goes into the glomerular capsule and then into the renal corpuscle. Some of the fluid is reabsorbed by the body.
What does a high concentration of Na-Cl in the renal tubule at the juxtaglomerular apparatus (JGA) most likely indicate?
insufficient NaCl reabsorption due to high GFR -- After glomerular filtration, NaCl is actively reabsorbed at many locations along the renal tubule. If the filtrate is moving through the tubule quickly, less reabsorption is possible, so more NaCl gets left behind. This means that at the JGA, the NaCl concentration within the filtrate will be high.

What are the most important nitrogenous wastes that are removed from blood by glomerular filtration?
urea
Which molecule would you expect to have the most difficulty crossing the glomerular filtration membrane?
albumin
What is themain functionof the proximalconvolutedtubules in urineformation?
reabsorption of most of the required substances from the filtrate
What is reasorption?
It means to retake up. The kidney filters water through itself to remove wastes but reabsorbs most of the water.
What is the main function of the proximal convoluted tubules in urine formation?
reabsorption of most of the required substances from the filtrate
What is the main function of the proximal convoluted tubules in urine formation?
reabsorption of most of the required substances from the filtrate
What happens to glucose that enters the nephron wit the filtrate?
In most cases it is reabsorbed. It there is too much, it will be "spilled" into the urine.
Which hormones is most likely to cause production of a concentrated urine?
Antidiuretic hormone(ADH) reabsorbs water from the collecting tubules of the kidney causing urine to become concentrated.
Once fluid enters the proximal convoluted tubule?
Once fluid enters the proximal convoluted tubule, the tubule reabsorbs most of the glucose, amino acids, and other essential nutrients back into the bloodstream. It also selectively reabsorbs water and ions to maintain electrolyte balance. Any waste products and excess substances not needed by the body are excreted in the urine.
