Kidney Flashcards
Outer surface of kidneys
Renal hilus (medial surface)
Renal sinus (space w/in kidney)
Protective layers of kidneys
(1) Renal capsule
(2) Adipose capsule
(3) Renal fascia
Inner regions of kidneys
(1) Renal cortex
(2) Renal medulla
(3) Renal pelvis
What are Calyces?
Extensions of the renal pelvis that collect urine and continuously drain it into the renal pelvis
What is the function of the kidney?
Filter the blood
What is the blood flow through the kidney?
(1) abdominal aorta
(2) renal artery
(3) 5 segmental arteries
(4) lobar arteries
(5) interlobar arteries
(6) arcuate arteries
(7) interlobular arteries
(8) afferent arteriole
(9) glomerulus
(10) efferent arteriole
(11) Peritubular capillaries / vasa recta
(12) interlobular vein
(13) arcuate vein
(14) interlobar vein
(15) renal vein
What is the nerve supply of the kidney?
Renal Plexus
Details of the Renal Plexus
- Nerve fibers follow renal arteries into each kidney
- Sympathetic innervation adjusts the diameter of the renal arteries to regulate blood flow
What is the Renal Capsule?
Layer of Kidney
- Innermost protective layer
- Tough, fibrous outer skin of kidney
- Protects from injury and traums
What is the Adipose Capsule?
Layer of Kidney
- Middle protective layer
- Outside renal capsule
- Fatty layer
- Cushion to protect from trauma
What is the Renal Fascia?
Layer of Kidney
- Outer protective layer
- Dense fibrous connective tissue
- Keeps the kidney held in place in the abdominal cavityW
What is the Renal Cortex?
Inner region of the kidney
- Projections = cortical columns
What is the Renal Medulla?
Inner region of the kidney
- divided into pyramids
What is the Renal Pelvis?
Inner region of the kidney
- Funnel-shaped tube
- connects to the ureter as it leaves the hilus
Renal arteries deliver ____ of blood per min
1200 mL
