E-learning 4 genitourinary system Flashcards
below the pelvic floor there is a region called the
perineum where the external ganglia extends from
the pelvic region can be divided into what
the greater (false) and lesser (true) pelvis
the lesser pelvis is what we know as the
pelvis cavity
female reproductive/sexual organs
the vagina
the uterus
the uterine (fallopian) tubes
the ovaries
male reproductive/sexual organs
the testes
the epididymides
the ductus deferentes
the seminal vesicles
the ejaculatory ducts
the prostate
the bulbourethral glands
what does the urinary system consist of
paired kidneys
paired ureters
bladder
urethra
what are the functions of the kidneys
excrete most of the waste products of metabolism
filter the blood, removing waste products and producing urine
controlling water volume and ion concentrations and in maintaining the acid/base balance of the blood
what is the outer layer of the kidney
cortex
what is the inner layer of the kidneys
medulla
the pyramids of the cortex drain into what?
minor calyces
around 2-3 minor calyces drain into each of the
major calyces
the major calyces drain into the
renal pelvis which empties through the ureters towards the bladder
the point where the structures enter or exit the kidney is known as the
hilum
the structure entering/exiting the hilum are
renal vein
renal artery
ureter
lymphatics and sympathetics
blood entering the the kidneys for filtration passes through knots of capillaries called…
glomeruli
the glomeruli are contained in the…
bowmans capsule
where are useful substances to the body reabsorbed
the proximal convoluted tubule
where is water reabsorbed
the loop of henle
where does are waste products that were not filtered out in the capsule secreted into the lumen
the distal convoluted tubule
where are water and ions are reabsorbed into the blood
in the collecting duct
what affect does antidiuretic hormone (ADH) have on the collecting duct
makes it more permeable allowing reabsorption of water
what and where do the renal arteries branch off
branch off the abdominal aorta just below the level of L1
what do they divide into to feed blood into the glomeruli
afferent arterioles
what arterioles run from the glomeruli and wrap around the nephron
efferent arterioles
