What can be interpreted from a high tranport rate (T_x)?

material was removed from ER by reabsorption
What can be interpreted from a negative tranport rate (Tx)?

material was added to ER by secretion
What can be interpreted form a Fractional Excretion ER/FL <1?

material was reabsorbed (ER has dropped from original FL)
What can be interpreted form a Fractional Excretion ER/FL >1?

material was secreted (ER rose from original FL)
What are the two routes of reabsorption transport?
- Paracellular
- Transcellular
What type of transport does glucose use to get from the apical to basolateral membrane?

Secondary active transport
What is the effect of AngII on Na reabsorption?
- 1) Activates Na/H pump
- 2) pushes H secretion
What is the effect of the SNS on Na reabsorption?

increased reabsorption
What is the effect of Parathyroid hormone on Na reabsorption?
- inhibites Na/Phosphate exchange
- pushes urinary phosphate excretion
What symptom is caused by mannitol?

Osmotic Diuresis b/c it can't be reabsorbed and it has to be accompanied by water. Na has to rediffuse into the lumen and bring more water in to excrete the Mannitol.
What happens to FL below Tubular Maximum?

reabsorbed
What happens to FL above tubular maximum?

excreted
What is threshhold?

Moment when a substance begins to be seen in urine
What does decreasing GFR do to threshhold?

Threshhold increases
How does competition for organic anion transporters boost antibody treatment?
- Many organic ions will compete for the same transporter
- Different organic ions can be utilized to help stop secretion of valuable anions that would generally bind to the specific transporter
