What makes up the renal portal system?
It is made up of the afferent arteriole which supplies blood to the kidneys. The glomerulus, which is the first capillary bed produces filtrate. The efferent arteriole takes blood from the kidneys. The peritubular capillary system, which is the second capillary bed reclaims most of the filtrate. Filtrate is what eventually becomes urine.
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 is the most common structure of volcanoes?
the most common structure of volcanoes is Yur MoMSz !
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 the structure that feeds most plants?
The structure that feeds most plants is soil, so the nutrients from it.
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 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
What is themain functionof the proximalconvolutedtubules in urineformation?
reabsorption of most of the required substances from the filtrate
Which molecule would you expect to have the most difficulty crossing the glomerular filtration membrane?
albumin
What is reasorption?
It means to retake up. The kidney filters water through itself to remove wastes but reabsorbs most of the water.

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.
