- segmental
- interlobar
- arcuate
- interlobular
- afferent glomerular arteriole
- **glomerulus**
- efferent arteriole
- pertibular capillaries
- vasa recta
- interlobular vein
- arcuate vein
- interlobar vein
- renal vein
what is the significance of the segemtnal arteries?
they supply individual sections of the kidney. so you can remove . portion of a kidney that is supplied by only one segmeental artery and be fine!
how would you describe the location of the kidneys? are they palpable
Abdominal caivity (retroperitoneal)
(retroperitoneal and adjacent to the posterior abdominal wall)
kidneys are located between vertebral levels T12-L3; right is slightly lower than left
kidneys are not palpable
they are well supported by fascia and change positiion slightly during inhalation
What is a renal lobe?
Medullary pyramid + Surrounding cortex
describe the sympathetic control of the kidney
Kidney T10-L1
Ureter and urinary bladder T11-L2
where are teh 3 spots a kidney stone can get lodged?
uritopelvic junction
iliac crest
as it enters the bladder
how much blood goes to the kidney?
the renal arteries, branches of the abdominal aorta, supply th kidneys with 20-25% of the cardiac output
an additional artery exists in 30% of the population
Describe the parasympathetic innervation of the renal system
parasympathetic input is derived from the vagus nerve (kidneys and ureter,) and pelvic splanchnic nerves (ureter and urinary bladder)
where does referred pain from the kidney go?
referred pain from the kindney and ureter is perceived in the T10-L2 spianl cord level distribution
