Tubular reabsoption:?
455154
Tubular reabsorption is a way to save things the body needs. The kidneys initially dump things from the blood into the glomerular filtrate (precursor to urine), then reabsorb some of it. Mostly water and salt, but also other ions and molecules such as folate. So, A's wrong.\n\nCreatinine is NOT reabsorbed in the tubules, although in very young (especially premature) neonates some of it does leak back across. So, B's wrong.\n\nAh, thanks for the extra info. The answer is C. Tubular absorption is both active and passive, but mostly active, and also D is internally wrong in that passive means NOT using ATP energy.

Two different procedures. Tube tying they can be reversed and unravel When the tubes are burnt they are burnt and this is not reversible

Indeed.  I read it in Scientific American.  They grind unusable organs that didn't make the cut for transplantation.  The spleen is especially high in heamocytes which fight the deleterious effects of male erectile dysfunction.  Future research is looking at whether soylent green can reduce the troublesome size of the main sphincter in those affectionatetly known as as*h**es.

c. Na - HCO3- reabsorption\nCOnserving FIltered Bicarbonate Ions: bicarbonate reabsorption:\nBicarbonate ions HCO3- are an important part of the bicarbonate bufffer sysem, the most important inorganic blood buffer. If this resevoir of base, or alkaline reserve, is to be maintained, the kidneys must do more than just eliminate enough Hydrogen ions to counter rising blood H+ levels. DEpleted stores of HCO3- have to be replenished. Dissociation of carbonic acid liberates HCO-3 as well as H+. WHile the tubule cells cannot reclaim HCO3- directly from the filtrate, they can and do shunt HCO3- generated within them as a result of H2CO3 splitting into the peritubular capillary blood. Accompanying HCO3- in the blood is the Na+ that enters the tubule cell as H- is pumped out. Thus reabsorption of HCO3- depends on the active secretion of H+ via an H+ -ATPase and more importantly NA+-H+ antiporter, which uses the lumen-to-tubule cell NA+ gradient to drive the transport process. In the filtrate H+ combines with filtered HCO3- generated within the tubule cells enters the blood- a one-for-one exchange. WHen large amounts of H+ are secreted, corresponding large amounts of HCO3- enter the peritubular blood, and the net effect is that HCO3- is almost completely removede from the filtrate.\nAdditional information abou the kidneys********below\nStep 3: TUbular Secretion:\nThe failure of tubule cells to reabsorb some solutes is an important means of clearing plasma of unwanted substances. A second such mechanism is tubular secretion-- essentially reabsorption in reverse. Substances such as H+,K+,NH4+, creatine and certaine organic acids move eithre from the blood of the pertibular capillaries through the tubule cells or directly from the tubule cells in the filtrate, Thus, the urine eventually excreted contains both filtrated and secreted substances. Tubular secretion is important for:\n1. Disposing of substances not already in the filtrate-certain drugs.\n2.ELiminating undesirab;e substances or end products that have been reabsorped by passive processes(urea and uric acid)\n3. Ridding the body of excess K+\n4. Controlling blood ph-----when blood ph drops toward the acidic end of its homeostatic rang the renal tubule cells actively secrete more H+ into the filtrate and retain more HCO3- and K+. as a result the blood pH rises and the urine drains off the excess H+

The loop of henle is the part of kidney i.e the uriniferous tubles where only water has reabsorbed out to blood therefore if we collected from that part than it is a diluted blood.

Yes, it can re-occur.Talk to a surgeon.

You may need to clarify your question. Are you talking about kidney stones or inability to urinate or painful urination? Have you tried  www.webmd.com ? Has your condition been diagnosed?

C.dont let your bladder exploed!!

There is a phrase - PPPPPP - Prior Preperation Prevents Piss Poor Performance.  If you revise, you will at LEAST do as well as if you have not revised, but also have the possibility (probability) of doing a lot better.  Revision is recommended, but I wish you luck!

Hey, are you talking about two "eyes" in the sides of the end of the foley tube that sits inside the bladder? If so, they're there to let the urine drain out more efficiently. If there was just the one big hole in the end of the tube that sits in the bladder, then "low-lying" urine would be too low to make it out of that hole.  That's why there are those two "eye" holes in the sides of the end of the tube.

do u mean hydronephrosis if so the definition of that is distention and dilation of the renal pelvis, usually caused by obstruction of the free flow of urine from the kidney.

I was born with a horseshoe kidney and my ureter was blocked.  They replaced it with a plastic tube, which so far has worked.  I had the operation at 9 years old and am now in my 40's. \nYou have to have it unblocked, otherwise all that poison stays in your body.

Can you imagine the scraping that would happen if they hung at the same level. No person has both testicles hanging at the same spot. One, I'm not sure which one, is always lower than the other! It most probably has nothing to do with the surgery you had!

Contain it in a tube.
