Renal corpuscle
Renal tubule
•Glomerular Capsule
What parts make up the nephron?
•Glomerulus
•Proximal tubule
•Nephron loop (of Henle) (Descending limb/ Ascending limb)
•Distal tubule
What is the glomerulus made of? capillaries
Function of a nephron filter blood and produce urine
Two nephron types juxtamedullary and cortical
-Long nephron loops deeply invade medulla
-Ascending limbs have thick and thin segments
juxtamedullary nephrons
-Important in production of concentrated urine
-found at the boundary of the cortex and medulla
-85% of all nephrons
cortical nephrons -short nephron loops
-efferent arterioles branch into peritubular capillaries around PCT and DCT
normal urine pH 4.6-8.0
glomerular filtration,
Three process of urine formation tubular reabsorption (proximal)
tubular secretion (distal)
1.)Reabsorption - moving substances with tubule into the blood.
2.)filtration - occurs in the glomerulus or renal corpuscle
How is urine made in the kidney?
3.)secretion
4.)filtration
driving force for filtration hydrostatic pressure or BP
What fluid comes out of the glomerulus? filtrate
mostly water, electrolytes, nutrients, and waste products. Glucose is normal in
What is filtrate? filtrate.
-similar to blood plasma
Tissue of bladder, ureter and part of transitional epithelium
urethera
average adult glomerular filtration rate is 125 mL/min or 180 L/day
Only water is absorbed in the descending limb. Na+ chloride is absorbed in the
Reabsorption in the Nephron Loop
ascending limb (no water).
Status of water coming out of nephron @ Lowest concentration (diluted)
loop?
Countercurrent mechanism (dilutes the urine). Can also create concentrated urine
from the Na+ absorbed in the ascending limb.
Process taking place in nephron loop?
where water and sodium comes out
-selectively moves substances from blood to filtrate in renal tubules and collecting
ducts
tubular secretion -From blood to tubular
-Usually in the distal tubule
-K+, H+, Uric acid, Penicillin are secreted
