URINARY SYSTEM Flashcards
(26 cards)
Where is urine produced?
Kidneys
Bean-shaped, retroperitoneal, lying against the dorsal body wall in the upper abdomen
Kidneys
What lies on top of each kidney?
Adrenal gland
Several structures enter or exits the concave surface of the kidney called? (Ureter and Renal Vein)
Renal Hilum
The kidneys have a rich blood supply under?
High pressure
Blood supply is facilitated by?
Renal Artery
Abdominal Aorta
Segmental Arteries
Interlobar Arteries
Outermost layer of internal structure of kidney, contains about 1mil nephrons.
Renal Cortex
Located in the cortex but their nephron loops dip in the medulla.
Cortical Nephrons
Have glomeruli that lie at the border of the cortex and medulla
Juxtamedullary Nephrons
2nd innermost segment, where renal pyramid is located.
Renal Medulla
Areas between the pyramids
Renal columns
Funnel shaped, within the renal sinus, collects urine from the pyramids and coveys it to the ureters.
Renal Pelvis
Consists of a specialized tubular structure and closely associated blood vessels.
Nephrons
Consists of a glomerulus (know of capillaries)
Renal corpuscle
Inner visceral layer of the capsule is made up of highly modified octopus like cells called podocytes.
Glomerular
Makes up the rest of the nephron. (3cm)
Renal Tubule
A region in renal tubule where water and solutes that passes from the blood flows.
Proximal Convoluted Tubule
Region of renal tubule where downward flow of fluid.
Descending Nephron Loop
Region in renal tubule where upward flow of fluid back into cortical region
Ascending Nephron Loop
Last region of RT
Distal Convoluted Tubule
Carrie’s the neuron to the tubules of the renal pyramids to the renal pelvis.
Medullary Collecting Duct
Renal Corpuscle is a structure much like an imagine of?
Fist thrusting ballon
Between the visceral and parietal layer responsible for collection of fluids.
Capsular Space
Small openings that allows passage of water and solutes.
Fenestrations
