|
what is the Proximal Convoluted Tubule |
the first segment of the renal tubule |
|
|
where is the entrance to the PCT |
opposite of where the afferent and efferent arterioles in glomerulus |
|
|
what is the epithleal lining of the PCT |
simple cuboidal, has microvilli on apical surface |
|
|
what does the epithelial lining of the PCT help with |
reabsorption also secretes substances into lumen |
|
|
what are the purpose of tubular cells |
absorbs organic nutrients, ions, water, and proteins from tubular fluid then release them into peritubular fluid(the IF around renal tubule) |
|
|
the loop of henle (nephron loop) descending limb |
fluid flows toward renal pelvis |
|
|
the loop of henle (nephron loop) ascending limb |
fluid flows toward renal cortex |
|
|
the loop of henle (nephron loop), each limb contains |
a thin segment and a thick segment |
|
|
the renal tubule turns toward the renal medulla and leads to what |
the loop of henle |
|
|
the thick descending limb has functions similar to what |
the PCT -it is the PCT, just in a different place |
|
|
the ascending limbs of the Juxta. nephrons in the medulla do what |
create a high solute concentration in the peritubular fluid |
|
|
the thin segments have what type of epithelium |
simple squamous epithelium |
|
|
are the thin segments permeable |
they are freely permeable to water but not to solutes |
|
|
what does water movement in the thin segments do |
helps to concentrate tubular fluid |
|
|
what is the eipthelium of the thick ascending limb |
cuboidal to columnar cells |
|
|
where does the thick ascending limb end |
at a sharp angle near the renal corpuscle ,where the DCT begins |
