urinary system Flashcards
– outer part containing the renal tubules
cortex
inner part made up of renal
pyramids.
Medulla
are the pipelines.
Ureters
the reservoir.
Urinary Bladder
a waste pipe.
urethra
They are two bean-shaped organs which lie in the
upper, posterior abdomen one on each side approximately
10cm. in length.
kidneys
– is a depression on the medial or inner
border where the renal artery, renal vein, the
lymphatic’s and pelvis enter the kidney
Hilum/Hilus
– includes the renal artery, vein,
lymphatic’s and renal pelvis.
Renal Pedicle
are two tubes about 10-12 inches in length
which extends from the kidney to the urinary bladder on
each side that conducts urine from the kidney to the Urinary
Bladder.
ureters
is the upper expanded funnel-shaped end of
the ureter which is in contact with the kidney.
renal pelvis
are two or three divisions of
the renal pelvis.
major calyces
are the cup-shaped divisions of the
major calyces, each minor calyx has a renal pyramid which is
made up of many collecting tubules and is cone-shaped with
its base directed towards the cortex.
minor calyces
Is a reservoir for the urine and lies in the pelvis behind the symphysis
pubis. It is in front of the rectum and in female, it is anterior to the uterus.
urinary bladder
Is the passage from
the UB to the outside. In female, it
is about 1.5 inches in length while
in male it is much longer and
passes through the prostate gland,
perineum and the entire length of
the penis for an approximate
length of 8 inches.
urethra
– having a small kidney.
micro kidney
– two kidneys are joined together across the midline of the
body.
horseshoe kidney
– large cysts are present in the kidneys.
Polycystic Kidneys
sometimes the superior
major calyx has a separate pelvis and a partial or complete separate ureter.
Double Kidney, Double Pelvis and Double Ureter –
– the kidney is not in its normal position.
ectopic kidney
the
bladder may lie outside the pelvis
and may have no anterior wall.
Exstrophy of the Bladder
the urethra opens
on the undersurface of the penis.
hypospadias
– the urethra opens on
the upper surface of the penis.
Epispadias
