1
Q
COMPONENTS OF URINARY SYSTEM
A
-Kidneys
-Bladder
-Ureters
-Urethra
2
Q
RENAL FUNCTIONS
A
- Acid-Base Balance
- Excretion of metabolic wastes
- Excretion of bioactive substances
- Secretion of renin
- Secretion of erythropoietin
- Conversion of Vitamin D
- Gluconeogenesis
3
Q
- stains darker than medulla
A
Cortex
4
Q
contains 8-12 renal pyramids containing a
renal lobe
A
Medulla (inner)
5
Q
- apical end contains renal papilla and minor calyx
that eventually become one of three major clayces - are separated by structures called renal columns
A
Renal Pyramids
6
Q
- Where renal artery and vein are located
- The ureter exits the kidney from here
A
Renal Hilum
7
Q
- Largest
- Divides into 2 segmental arteries at hilum
A
Renal Artery
8
Q
- Branch from segmental arteries
- Extend between renal pyramids towards
corticomedullary junction
A
Interlobar Arteries
9
Q
- Branches from interlobar arteries
A
Arcurate Arteries
10
Q
- Branches from arcurate arteries
- Extend all the way to renal cortex
A
Interlobular Arteries
11
Q
- Where blood is filtered in the kidney
- drained by efferent arterioles
A
glomeruli
12
Q
- branch into peritubular capillaries
A
Efferent arterioles
13
Q
Functional units of the kidney
* 1- 4 million
A
NEPHRONS
14
Q
Major Divisions of Nephron
A
- Renal Corpuscle
- Proximal Tubule
- Loop of Henle
- Distal Tubule
- Connecting Tubule
15
Q
- links nephron to collecting ducts
A
Connecting Tubule
