Q

mesentary

A

a double layer of peritoneum

  • flap-like
  • occurs as result of invagination of peritoneum by an organ
  • connects an intraperitoneal organ w/ body wall (V.A.N.)
  • sets pathway for vasculature

(ie) mesentary of small intestine
(ie) transverse mesocolon

Q

omenta

A

a double, two-layered folds of peritoneum (2 sheets, 4 layers)

  • create secondary sac
  • mostly fat
  • contains vessels and nerves
  • travel from stomach/duodenum to adjacent organs

(ie) greater and lesser omentum

Q

clinical application of peritoneal fluid

Study These Flashcards
A

subphrenic recess, hepatorenal recess, and paracolic gutters make it easier for infections and cancer to spread

  • most problems on right side
  • causes perforated duodenal ulcers y appendicitis
24
Q

ascites

Study These Flashcards
A

abnormal build up of serous fluid in abdomen

- symptoms: swelling and distending of abdomen

25
causes of ascites
``` heart failure mechanical injury peritonitis infection portal hypertension starvation (lack of protein) cirrhosis (liver problems) ```
26
paired major abdominal arteries
L/R inferior phrenic artery L/R renal artery L/R gonadal artery L/R lumbar artery GIRLs got to the bathroom in PAIRS
27
unpaired major abdominal arteries
celiac artery superior mesenteric artery inferior mesenteric artery median sacral artery
28
celiac artery branches
**branches at T12 (1) left gastric artery (2) splenic artery (3) common hepatic artery
29
celiac artery supplies
``` esophagus stomach liver duodenum gall bladder spleen pancreas ``` Every Student Likes Doing Grad School Papers
30
superior mesenteric artery supplies
``` small intestine secum appendix transverse colon ascending colon ``` superior mesenteric artery = S (i) S A T A
31
superior mesenteric artery branches
``` inferior pancreaticoduodenal middle colic right colic iliocolic jejunal/ilial ``` In Peru Mothers Rape Infants and Juveniles
32
inferior mesenteric artery supplies
``` transverse colon descending colon sigmoid colon rectum upper 1/2 anal canal ``` Today Dr. Sanchez Rapes Us
33
inferior mesenteric branches
left colic sigmoid superior rectal Lupe Can't Sample Sweets Regularly (chocolate chin)
34
medial sacral artery supplies
sacrum
35
artery
collacteral circulatory routes - ensures adequate blood flow to distal areas - provides alternative pathways for blood flow during restrictive movements
36
artery subtypes
arterial arcades (loops) marginal artery arteriae rectae
37
arterial arcades (loops)
anastomotic loops between adjacent branches collectively top of loops are marginal arteries
38
marginal artery
parallels colon | - connected to arteriae rectae
39
arteriae rectae
around and w/in gut tube - does not communicate w/ each other - connected to marginal artery
40
major abdominal veins
inferior vena cava azygos system hepatic portal system
41
inferior vena cava
union of two common iliac veins | - other tributaries (naming similar to arterial)
42
portal system
two capillary beds in connection consecutively before turning to heart - needed for cleaning out fluids (liver) from GI tract before entering azygos
43
hepatic portal system
union of: | splenic vein + superior mesentary vein
44
purpose of hepatic portal system
(1) modify nutrient concentration and metabolism in blood | (2) remove bacteria, toxins, drugs
45
clinical application of hepatic portal system
drug power and necessary dosage depends on whether drugs goes to liver or not - goes through liver, need larger dose
46
portal hypertension
results from increased venous pressure in system - obstruction of portal vein - obstruction of liver (tumor, cirrhosis)
47
portal hypertension can lead to
varicose veins (stomach to colon) hemorrhoids (anus) ascites internal bleeding
48
sympathetic nervous system of abdominal organs
SNS decreases peristalsis and causes vasoconstriction - abdominal sympathetic ganglia (paravertebral) (T5 - L3) - splanchnic nerves (greater, lesser, least and lumbar) - prevertebral (collateral) ganglia
49
types of prevertebral (collateral) ganglia
(1) coliac (2) aorticorenal (3) superior mesentary (4) inferior mesentary prevertebral ganglia CASI (like)
50
parasympathetic nervous system
CNX vagus nerve | pelvic splanchnic nerves
51
CNX vagus nerve supplies
esophagus to transverse colon | *including accessory organs along the way
52
pelvic splanchnic nerves supply
descending colon to rectum
53
lymphatic drainage
characterized by a series of nodes associated with the abdominal aorta - cisternal chyli
54
cisterna chyli
elongated sac that pools from abdomen and lower extremities - becomes thoracic duct (into left) - location: right side of aorta @ L1
55
spleen
largest solid lymphatic organ - location: left hypochondrium @ 10th rib - arterial supply: splenic artery - venous drainage: splenic vein
56
FCN of spleen
(1) lymphopoieisis - make lymph (2) filter y destroy aged RBC (3) store RBC y platelets
57
clinical application of spleen
humans can live without a spleen | - the liver and bone marrow will take over spleen job
