Proximal Convoluted Tubule
Rick Satterfield
Most solute reabsorption occurs in the proximal convoluted tubule (PCT) of the nephron. PCT is responsible for reabsorbing about 65-70% of filtered sodium, water, glucose, and amino acids in the urine back into the bloodstream. It also plays a significant role in reabsorbing other solutes, such as bicarbonate ions and ions like potassium and chloride.

Which section of the nephron performs MOST of the glucose and water reabsorption?
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 water reabsorption occur?
Between tubular elements and vascular elements of the nephron beginnings with the proximal convoluted tubule and continuing at least part way into the distal tubule.
Where in the nephron is most glucose reabsord?
no
Which of the choices below are the most important hormone regulators of electrolyte reabsorption and secretion?
angiotensin II and aldosterone
Which section of the nephron performs MOST of the glucose and water reabsorption?
proximal convoluted tubule
Most materials are reabsorbed from nephron tubules into surrounding blood vessels by the process known as?
Selective reabsorption
Where does most re-absorption of water occur in the digestive system?
large intestine.in the large intestine

Where does Most electrolyte reabsorption by the renal tublues occur?
Proximal tubule
Where does water reabsorption occur?
Between tubular elements and vascular elements of the nephron beginnings with the proximal convoluted tubule and continuing at least part way into the distal tubule.
The U-shaped segment of the nephron is the?
The most distal portion of the nephron is the
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.
Where in the nephron is most glucose reabsord?
no
What ion cation do most diuretics work by blocking the renal reabsorption?
Potassium
What is themain functionof the proximalconvolutedtubules in urineformation?
reabsorption of most of the required substances from the filtrate
Is water a major solute?
Water is not a solute, it is the most important solvent.
