Urinary Flashcards
1
Q
- histologically apparent substructure of the renal cortex composed of glomeruli and proximal tubules.
A
Cortical labyrinth
2
Q
- An anatomical unit of the kidney composed of the medullary pyramid and the overlying cortex.
A
Lobe (renal)
3
Q
- An anatomical subunit of a renal lobe that is centered on a single medullary ray.
A
Lobule (renal)
4
Q
- Collections of renal tubules coursing from the renal cortex to the medulla and centered around a collecting duct.
A
Medullary rays
5
Q
- The process by fluid and molecules selectively pass across the glomerular filtration barrier (plasma -> urine). The ultrafiltrate is dependent on concentration gradients and hydrostatic blood pressure.
A
Ultrafiltration (renal)
6
Q
-cup-like structures receiving urine from the collecting ducts where it passes on to the renal pelvis and ureter
A
Calyces
7
Q
-arteriole carrying blood from the glomerulus to the capillary beds around the convoluted tubules and loop of Henle; portion of the portal system
A
Efferent arteriole
8
Q
- tuft of capillaries surrounded by Bowman’s capsule; filters the blood based on size
A
Glomerulus
9
Q
- functional units of the kidney that carry out all filtration and modification to produce urine; consist of renal corpuscles, proximal and distal convoluted tubules, and descending and ascending loops of Henle; drain into collecting ducts
A
Nephrons
10
Q
- inner region of kidney containing the renal pyramids
A
Medulla
11
Q
- second capillary bed of the renal portal system; surround the proximal and distal convoluted tubules; associated with the vasa recta
A
Peritubular capillaries
12
Q
- extensions of the renal cortex into the renal medulla; separates the renal pyramids; contains blood vessels and connective tissues
A
Renal columns
13
Q
- outer part of kidney containing all of the nephrons; some nephrons have loops of Henle extending into the medulla
A
Renal cortex
14
Q
- adipose tissue between the renal fascia and the renal capsule that provides protective cushioning to the kidney
A
Renal fat pad
15
Q
- recessed medial area of the kidney through which the renal artery, renal vein, ureters, lymphatics, and nerves pass
A
Renal hilum
