Filtration with filtration barrier |
Renal Corpuscle |
|
|
Filtration barrier of renal corpuscle |
Endothelial cell Fused basal lamina Filtration slits |
|
|
Resorption of 80 % of water, sodium, and chloride (reducing volume of ultrfiltrate); resoption of 100% of protein and amino acids, glucose, and bicarbonate; sodium pump in Ballarat membrane: ultrafiltatre is isotonic with blood |
Proximal tubule |
|
|
Completely permeable to water and salts (reducing volume of ultrafiltatre) Ultrafiltrate is hypotonic with respect to blood: urea enters lumen of tubule |
Descending thin limb of Henle's loop |
|
|
Impermeable to water, permeable to salts; sodium and chloride leave tubule to enter renal interstitium Ultrafiltrate is hypotonic with respect to blood: urea leaves renal interstitium and enters lumber of tubule |
Ascending limb of Henle's loop |
|
|
Impermeable to water, chloride, and sodium leave tubule to enter rebel interstitium Ultrafiltrate becomes hypotonic with respect to blood: chloride pump in basolateral cell membrane is responsible for the establishment of osmotic gradient in the interstitium of outer medulla |
Ascending thick limb of Henle's loop |
|
|
Monitors sodium level and volume of ultrafiltrate in lumen of distal tubule Contacts and communicates with juxtaglomerular cells |
Macula densa |
|
|
Synthesize and secrete renin into bloodstream |
Juxtaglomerular cells |
|
|
Initiates the reaction for the eventual formation of angiotensin 2 |
Renin |
|
|
Respond to aldosterone by reabsorbing sodium and chloride from lumen Ultrafiltrate becomes more hypotonic (I'm the presence of aldosterone): sodium pump in basolateral membrane: potassium is secreted in to lumen |
Distal convoluted tubule |
|
|
In the presence of ADH, water, and urea leave the lumen to enter the renal interstitium Urines becomes hypertonic in the presence of ADH: urea in the interstitium is responsible for gradient of concentration in interstitium of the inner medulla |
Collecting tubule |
