Abd Cavity - Internal Organs Flashcards
the pelvic cavity contains the terminal parts of
- uterus
- bladder
- rectum
- pelvic genital organs
- blood vessels
- lymphatics & nerves
what organs can be found in the right upper quadrant (RUQ)
- R. lobe of liver
- gallbladder
- duodenum
- head of pancreas
- R. adrenal gland
- R. kidney
- superior part of ascending colon
- R. of transverse colon
what organs can be found in the right lower quadrant (RLQ)
- cecum
- appendix
- most of ileum
- inferior part of right uterine tube
- R. ovary
- ascending colon
- R. ureter
- R. spermatic cord
what organs can be found in the left upper quadrant (LUQ)
- L. lobe of liver
- spleen
- most of stomach
- jejunum and proximal ileum
- body &tail of pancreas
- L. adrenal gland
- L. kidney
- superior part of descending colon
- L. half of transverse colon
what organs can be found in the left lower quadrant (LLQ)
- sigmoid colon
- inferior part of descending colon
- L. ovary
- L. uterine tube
- L. ureter
- L. spermatic cord
inner lining of the abdominal cavity
peritoneum
functions of peritoneum
- provides support and allows some mobility
- lubricates the viscera to decrease friction
organs that are entirely encased in peritoneum
intraperitoneal
organs that have peritoneum on one surface with the rest of the organ underneath
retroperitoneal
sheets of peritoneum attached to the stomach
omentum
the gastrointestinal (GI) tract includes the
- stomach, small/large intestine to the anus
- fairly straight tube that descends from the pharynx
- pierces the diaphragm just to the left of the midline
- allows food to pass from oropharynx to stomach
esophagus
what happens when the folds of the muscular wall in the esophagus is stimulated
initates the cough reflex
does the omentum of stomach carry blood vessels?
yes
most absorption occurs here
small intestine
connects the small intestine to the large intestine at the ileocecal valve
cecum
connects the small intestine to the large intestine at the ileocecal valve
cecum
second part of the large intestine is known as the
colon
rises out of right iliac fossa to level of right kidney; takes a 90° turn becoming the right colic (hepatic) flexure
ascending colon
crosses most abdominal structures horizontally to reach spleen; bends at 90° to form left colic (splenic) flexure
transverse colon
descends on the left side from left colic flexure; terminates after it reaches pelvic rim and becomes sigmoid colon
descending colon
it doubles back on itself to the midsacral level where it becomes the rectum
sigmoid colon
third part of the large intestine
rectum & anus
most distal part of large intestine that lies within abdominopelvic cavity; terminates into anus
rectum
a sphincter that controls defication; contains external and internal sphincter
anus
the remnant of the obliterated umbilical vein
ligamentum teres
splenic vein drains in to the
hepatic portal system
recieves the vessels and nerves of the kidney
renal hilus
function of adrenal glands
release hormones in response to stress: cortisol, aldosterone, epinephrine, norepinephrine
adheres directly to the kidney surface
adrenal capsule
protects the kidneys from blows acting as a cushion
perineal and pararenal fat layers
protects the kidneys from blows acting as a cushion
perineal and pararenal fat layers
urine-producing functional structure of the kidney
nephrons
initial filtering portion of a nephron located in the renal cortex
renal corpuscle
renal tubule passes from the renal cortex deep into the
medullary pyramids
collects urine draining from papillae
major and minor calyces
path of urine once in papilae
papilae - minor/major calyces - renal pelvis - ureter
transports urine to bladder for storage
ureter
urine-carrying tubes
renal pelvis and calyces
the internal area demarcated by the internal urethral & urteric orifices
trigone of bladder
conveys urine from bladder to the external urethral orifice and provides an exit for semen
the male urethra
conveys urine from bladder to the external urethral orifice and provides an exit for semen
the male urethra
