tubules traveling from the cortex to the medulla with a similar appearance as proximal convoluted tubules. (histologyguide.com)
Mainly the proximal convoluted tubules are affected. (greek.doctor)
Nephron5
The nephron is made of 2 main parts: the renal corpuscle and the renal tubule. (innerbody.com)
The nephron consists of a glomerulus and a series of tubules ( Figure 1.2 ). (abdominalkey.com)
Tubules are lined by a continuous layer of epithelial cells, each of which possesses characteristic morphology and function depending on its location in the nephron. (abdominalkey.com)
The S3 segment of the proximal tubule, which maintains the delicate balance between high O 2 demand and low basal O 2 tension in the corticomedullary region, is the portion of the nephron most vulnerable to ischemia (Parker et al. (cellphysiolbiochem.com)
The proximal convoluted tubule is the portion of the nephron that attaches to the collecting duct. (studyhubpro.com)
Urine8
The ascending limb drains urine into the distal convoluted tubule. (wikipedia.org)
During the maintenance phase, renal tubule injury is established, the GFR stabilizes at the level well below normal, and the urine output is low or absent. (medscape.com)
A series of tubes called the renal tubule concentrate urine and recover non-waste solutes from the urine. (innerbody.com)
The renal tubule carries urine from the glomerular capsule to the renal pelvis. (innerbody.com)
The tubule cells that line the proximal convoluted tubule reabsorb much of the water and nutrients initially filtered into the urine. (innerbody.com)
Urine next passes through the loop of Henle, a long straight tubule that carries urine into the renal medulla before making a hairpin turn and returning to the renal cortex. (innerbody.com)
Urine is formed by glomerular filtration and modified by the tubules, leaves the collecting ducts and drains sequentially into the calyces, renal pelvis, ureter, and finally into the bladder. (abdominalkey.com)
Although urine is finally modified in subsequent tubules, the proximal tubule is the main site for both NaCl and NaHCO 3 reabsorption. (cellphysiolbiochem.com)
Reabsorb3
This causes the proximal tubules to be unable to reabsorb sodium, meaning that more sodium reaches the distal tubules. (greek.doctor)

Angiotensin I is converted to Angiotensin II with the substance called renin in the distal renal tubules of the kidneys. (triadofhealth.net)

Reabsorption5
About 85% of the filterate formed is reabsorbed in a constant, unregulated fashion by the proximal convoluted tubule and descending limb of Henle's loop, called mandatory reabsorption. (apboardsolutions.guru)
As I shall show later on, lasix and lisinopril could have raised her risk for kidney damage from crystals, the former because of increased proximal tubule reabsorption , the latter because of reduced glomerular filtration rate . (uchicago.edu)
By depleting the body of sodium and water, these drugs would also raise proximal tubule reabsorption and lower glomerular filtration. (uchicago.edu)
There appears to be no direct or indirect coupling between sodium and chloride or bicarbonate reabsorption in the distal colon. (veteriankey.com)
Active chloride reabsorption and bicarbonate secretion occur in the distal colon. (veteriankey.com)
Glomerulus1
At the far end of the glomerular capsule, opposite the glomerulus, is the mouth of the renal tubule. (innerbody.com)
Interstitium4
Salt moves out of the tubule and into the interstitium due to osmotic pressure created by the countercurrent system. (wikipedia.org)
Intrinsic ARF (40% of ARF cases) is the result of structural damage to the renal tubules, glomeruli, interstitium, or renal vasculature. (medscape.com)
Many diseases don't primarily affect the glomeruli but rather the tubules and interstitium. (greek.doctor)
This increases the backward pressure in the tubules, which forces filtrate to leak through the damaged tubules and back into the interstitium, a process called backleak . (greek.doctor)
Macula densa1
At the junction of the thick ascending limb and the distal convoluted tubule are a subset of 15-25 cells known as the macula densa that are part of renal autoregulation through the mechanism of tubuloglomerular feedback. (wikipedia.org)
Segment4
Especially the straight segment of the proximal tubule and the straight segment of the distal tubule (the thick ascending limb) are vulnerable to ischaemic damage. (greek.doctor)
A small difference is that it is the convoluted segment of the proximal tubule which is most susceptible to toxic damage. (greek.doctor)
have suggested that the pronephric duct as described traditionally may consist of subregions which are analogous to portions of the tubule segment of mammalian and other fish nephrons. (zfin.org)
2015). Based on this theory, the reversed mode of NCX in proximal tubules, particularly the S3 segment, is required. (cellphysiolbiochem.com)
Thick3
the thick portion is also known as the distal straight tubule, in contrast with the distal convoluted tubule downstream. (wikipedia.org)
Ischaemic ATN is characterised histologically by lesions in the straight portions of the proximal tubule and ascending thick limbs. (greek.doctor)
Distal part of testis continues into a short and thick twisted tube, the vas deferens. (wandofknowledge.com)

The other transverse sinus is the continuation of the straight sinus. (bvsalud.org)
Membranes3
The functional significance of the Na + /Ca 2+ exchanger (NCX) in basolateral membranes in the proximal tubule remains controversial. (cellphysiolbiochem.com)
1989), however, suggested that there is no NCX in basolateral membranes in proximal tubules but that instead, intracellular calcium pools within the mitochondria and elsewhere contribute to Na + /Ca 2+ exchange. (cellphysiolbiochem.com)
The localization of NCX in basolateral membranes of proximal tubules is also controversial. (cellphysiolbiochem.com)
3. All of the filtered bicarbonate is normally reabsorbed in the first half of the distal tubule. (neetprep.com)
