Renal Anatomy Flashcards
Kideys are: primary retroperitoneal secondary retroperitoneal
Primary retroperitoneal because they started off in the retroperitoneam and stayed that way
Which kidney is lower and why?
right kidney is lower because of the liver
What is the anterior to posterior relationship of the: renal: pelvis/vein/arteriy
anterior–> posterior renal vein–renal artery–renal pelvis
apx weight of the kidney
150 for male and 135 for femal
Medulary pyramid + surrounding cortex =
Renal lobe
What are the three ‘layers’ of the kidney starting out moving in?
Renal capsule
Renal cortex
renal medula
contains the renal corpuscles and the renal tubules except for parts of the loop of Henle
Where ultrafiltration occurs
Renal Cortex
contains the structures of the nephrons responsible for maintaining the salt and water balance of the blood.
Hypertonic to the filtrate in the nephron and aids in the reabsorption of water.
Renal medulla
Renal capsule is made of
connective tissue
The renal artery divides into _______–> Lobar arteries–> Interlobar arteries–> ______arteries–>Interlobular arteries
Segmental Arteries
Arcuate Arteries
Describe the path blood takes in the kidney starting with the renal artery
Refer to image
What feeds into the glomeruli
afferent arterioles
Kidneys receive ____% of blood from CO from the renal arteries and abdominal aorta
20%
Sympathetic innervation of
Kidney:
Ureter:
Urinary Bladder:
Kidney: T10-L1
Ureter: T11-L2
Urinary Bladder: T11-12
What Parasympathetic innervation do we have at the kidneys?
Vagus nerve and Pelvic splanchnic
What stuctures are near the kidneys from posterior view?
Green = Respiratory Diaphragm
Salmon = Transversus abdominals
Yellow= Quadratus
Purple = psoas major
How are kidneys protected damage within the body cavity?
adipose tissue surrounding them acts as shock absorbers
Explain the anatomy of the ureters compared to the iliac artery/vein
Water runs over the bridge
ureters are on top of them
In general, referred pain from the kidney and ureter is precieved in the ______ spinal cord level distribution
T10-L2
An additional renal artery appears ____% of the time
30%
Blood supply of the ureter comes from:
branches of arteries encountered along its course from kidney to urinary bladder
Normally the kidneys are:
unpalpable
The kidneys are ________ and adjacent to _______ abdominal wall
adjacent
posterior
Kidneys are located btwn vertebral levels ____ and ____
T12 and L3
