7.1 Anatomy of the Urinary System Part 2 Flashcards
Where do the cortical columns extend to?
between the renal medulla pyramids
Where are the glomerular capsule and distal and proximal convoluted tubules located?
in the cortex
Where is the renal medulla located?
just inside of the renal cortex
What does the renal medulla contain?
renal pyramids
Where do the renal pyramids point?
toward the center of the kidney
What is located within the renal medulla?
loop of henle
collecting ducts
Where is the renal pelvis located?
centermost section of the kidney
What is the renal pelvis?
funnel shaped tube that connects to the ureter
Where does the ureter exit from?
hilus
What are calyces?
extensions of the pelvis that collect urine and drain it into the pelvis and ureter
How much blood do the renal arteries deliver to the kidney?
1200 ml of blood per minute
Where is the blood delivered from to the kidneys?
aorta
What is the division of arteries from renal arteries?
renal arteries - segmental arteries - lobar arteries - interlobar arteries - arcuate arteries - interlobular arteries - afferent arterioles
What do the afferent arterioles supply?
glomeruli
Where does blood travel after filtration in the glomeruli?
efferent arterioles - peritubular or vasa recta capillaries - interlobular veins - arcuate veins - interlobar veins - renal vein
How do the kidney and nervous system interact?
renal plexus
Where does the renal plexus travel?
fibers follow the renal arteries to reach the kidney
What does the sympathetic nervous system do to the kidneys?
adjusts the diameter of the renal arteries regulating renal blood flow
What do the ureters begin as?
continuation of the renal pelvis
What are the ureterovesical valves?
sphincters located where the ureters enter the bladder
