Module 12 - Renal Failure Flashcards
Renal Medulla
Inner part of the kidney made of renal pyramids and tubular structures
Renal Cortex
Outer layer of the kidney
Renal Artery
supplies blood to the kidney
Renal Pyramid
channels output to renal pelvis for excretion
this is where the collecting ducts come together
Renal Calyx
channels connecting the renal pyramids to the renal pelvis
Renal Vein
about 99% of filtered blood is circulated through this vein
1% contains waste products and undergoes further processing
Renal Pelvis
Blood containing waste products forms urine here and is channeled away
Ureter
tube that terminates in the urethra
A lot of blood exchange happening in the kidneys occurs at …
the distal and proximal tubules (they help maintain acid base, fluid and electrolyte balances)
Both the distal and proximal tubules are involved in ___
reabsorption
Along with reabsorption, the distal tubule is involved in ___
excretion
Filtrate
the filtering fluid in the kidneys until nothing else is removed in which is becomes urine and is excreted
Parenchymal Tissue of the Kidney
Nephron
___ flow goes to the nephron
Arteriole
Afferent Arteriole
carries arteriole blood toward the Bowman’s Capsule
hydrostatic pressure going into the glomerulus
Efferent Arteriole
Carries arteriole blood away from the Bowman’s Capsule
hydrostatic pressure coming out of the glomerulus
What controls arteriole flow
pressure
Bowman’s Capsule
capsule surrounding the filter of the kidney, the Glomerulus
contains the glomerulus and acts as a filter for the urine/filtrate
Glomerulus
the filter of the kidney
A network of twisted capillaries acting as a filter for the passage of protein free and RBC free filtrate
What is abnormal to see go through the Bowmans capsule and why?
Normally in health, proteins and RBCs are too large to get through the bowman’s capsule - if proteins or RBC are in urine than that is abnormal
What is the pathway to through the nephron
Afferent Arteriole –> Bowmans Capsule and Glomerulus –> Proximal Convoluted Tubule –> Loop of Henle –> Distal Convoluted Tubule –> Collecting duct –> renal pyramids –> ureters –> Bladder –> Urethra and exit
Medullary Nephrons
Nephrons that go deeper into the kidney
since they are deeper they have greater urine concentrating ability, but will be damaged sooner
Cortical Nephrons
more shallow nephrons with lower concentrating ability
Why are Medullary nephrons injured before cortical ones?
Because of impaired/compromised blood flow
