Abdominal Viscera and Vessels Flashcards
what organs make up the digestive system?
digestive tube (mouth pharynx alimentary canal), liver, pancreas, salivary glands
alimentary canal
esophagus, stomach, intestine
esophagus
cervical, thoracic, and abdominal regions
all striated in dog
2 stomach sphincters
cardiac and pyloric
4 stomach regions
cardiac, fundus, body, pyloric
3 parts of small intestine
duodenum, jejunum, ileum
5 duodenal regions
cranial flexure, descending duodenum, caudal flexure, ascending duodenum, duodenal-jejunal flexure
4 parts of large intestine
cecum, colon, rectum, anal canal
5 regions of colon
ascending colon, right colic flexure, transverse colon, left colic flexure, descending colon
where is the anal canal cavity wise?
retroperitoneal
anus
external opening of anal canal
2 sphincters of anal canal
internal anal sphincter (smooth m.)
external anal sphincter (striated m.)
function of liver
secretes bile salts to emulsify fats
bile stored in gall bladder
6 lobes of liver
caudate lobe, right lateral, right medial, quadrate lobe, left medial, left lateral
function of pancreas
secretes proteolytic enzymes into duodenum and endocrine secretions (insulin)
structure of pancreas
left lobe along stomach, body, right lobe along duodenum
2 ducts of pancreas
pancreatic duct (small) empties into major duodenal papilla with bile duct accessory pancreatic duct (large) empties into minor duodenal papilla
function of kidney
remove waste products from blood (urine)
regulate fluid/salt balance (blood osmotic pressure)
what is the renal hilus?
where vessels and the ureter enter the kidney
kidney position
right kidney more cranial than left
right cupped by liver
left is loosely attached
feline kidneys are caudal
renal capsule
fibrous tissue surrounding the kidney
renal cortex
superficial tissue containing vascular glomeruli in kidney
renal medulla
deep tissue of kidney
renal pyramid
medula between interlobar vessels in kidney
ureter
conveys urine from kidney to urinary bladder
renal pelvis
expanded proximal end of ureter in renal sinus of kidney
pelvic recess
lateral expansion of renal pelvis between interlobar vessels
function of spleen
reservoir for blood cells
filters particles and old red blood cells from blood
lumbar artery
supply vertebral column, spinal cord, epaxial m., and skin on back
common trunk
supply abdominal wall, adrenal gland via cranial abdominal artery and diaphragm
deep circumflex iliac artery
supply abdominal wall caudally
celiac artery
supplies cranial abdominal viscera
gastric and gastricepiploic branches to stomach
cranial mesenteric artery
supplies duodenum, ascending colon, transverse colon and pancreas
caudal mesenteric artery
supplies descending colon and rectum
external iliac arteries
supplies pelvic limb
internal iliac arteries
supplies pelvis wall and viscera
median sacral artery
becomes median caudal of tail
function of portal vein
convey blood between two capillary beds of alimentary tract and liver sinusoids
what forms the portal vein?
cranial and caudal mesenteric veins anastomose
splenic v. and gastroduodenal v. join before entering liver
circulation sequence of portal vein
celiac, cranial, and caudal mesenteric arteries, alimentary capillaries, stellite veins, portal vein, hepatic sinusoids, hepatic vein, caudal vena cava
cysterna chyla
convergence of mesenteric lymph ducts just caudal to diaphragm
