Exam 3 - Beginning of Study Guide Flashcards
Location of Rectus abdominus
anteriorly prominent muscle of abdomen
Relation of Rectus abdominus to physical exam
prominence when supine pt raises head; relax for exam >> ask pt to bend knees
Location of Internal/external obliques
located laterally
Location of Linea alba
tendinous band, midline, between rectus abdominis muscles - from xiphoid process to symphysis pubis, contains umbilicus
Location of Inguinal ligament
anterior superior spine of ilium to each side of pubis
Skeletal landmarks important in abdominal exam
xiphoid process, costal margin, iliac crest, anterior superior iliac spine (ASIS), symphysis pubis, pubic tubercle, inguinal ligament (attaches to ASIS, pubic tubercle); promontory (part of sacrum)
Important vascular structures in abdomen
abdominal aorta, common iliac arteries (umbilicus), splenic artery, renal arteries; celiac trunk (blood supply)
Abdominal organs
liver, gallbladder, small intestine (duodenum, jejunum, ileum), colon (cecum, ascending colon, transverse colon, descending colon, sigmoid colon), spleen, stomach, pancreas; kidneys, adrenal glands, ureters, bladder, uterus, ovaries, fallopian tubes; ,
Shape of stomach
flask-shaped;
Function of stomach
secretes HCl, digestive enzymes (pepsin - digests proteins, gastric lipase - emulsifies fats); very little absorption
Functional sections of the stomach
3 sections: fundus, body (mid 2/3), pylorus (most distal portion, narrows, terminates in pyloric orifice);
Vascular supply of the stomach
supplied by (gastroduodenal, L gastric, R & L gastro-omental, short gastric)
Size of liver
heaviest organ in body (~3 lbs in adults);
Function of liver
drains into bile duct –> hepatic duct –> cystic duct from GB to form common bile duct
Secretions of liver
liver cells secrete bile
Functional sections of the liver
four lobes - functional units;
Location of the liver
inferior surface touches gallbladder, stomach, duodenum, hepatic flexure of colon;
Vascular supply of the liver
hepatic artery (brings oxygenated blood directly from the aorta), portal vein (brings venous blood rich in products of digestion, absorbed directly from GI tract), venous return (3 hepatic veins carry blood from liver to inferior vena cava
Shape of gallbladder
sac-like, pear-shaped organ;
Size of gallbladder
~4 in long;
Function of gallbladder
concentrate & store bile from liver
Location of the gallbladder
recessed to inferior surface of liver;
Vascular supply of the gallbladder
supplied by cystic artery
Size of small intestine
21 feet long (duodenum = 12 in (1 foot), jejunum = 8 ft, ileum = 12 feet);
Function of small intestine
completes digestion by way of action of pancreatic enzymes, bile, several enzymes; nutrient absorption due to tremendous surface area from circular folds/villi
Functional sections of the small intestine
Duodenum; Jejunum; ileum
Vascular supply of the small intestine
superior mesenteric artery and branches
Size of colon
length 4.5-5 ft, diameter 2.5 in;
Function of colon
live bacteria (decompose undigested food residue, unabsorbed amino acids, cell debris, and dead bacteria –> putrefaction
Colon secretions
mucus glands secrete large quantities of alkaline mucus (lubricate intestinal contents, neutralize acids formed by intestinal bacteria)
Functional sections of the colon
Cecum; ascending colon; hepatic flexure; transverse colon; splenic flexure; descending colon; sigmoid colon; rectum; anal canal
Vascular supply of the colon
inferior mesenteric artery and branches
Function of spleen
white pulp (makes up most of spleen, lymphoid tissue, part of reticuloendothelial system - fliters blood and manufactures lymphocytes & monocytes); red pulp (capillary network, venous sinus system, allows for storage and release of blood, permits to accommodate up to several mL at once)
Functional sections of the spleen
White pulp; red pulp
Location of the spleen
LUQ, above left kidney, below diaphragm;
Vascular supply of the spleen
supplied by celiac trunk- splenic artery, and splenic vein
Function of pancreas (exocrine)
exocrine function: acinar cells digest juices containing inactive enzymes for the breakdown of proteins, fats, carbs; pancreatic duct runs length of organ empties into duodenum at duodenal papilla, along common bile duct; in duodenum, digestive enzymes are activated
Function of pancreas (endocrine)
islet cells produce insulin, glucagon; secrete both into blood to regulate blood glucose levels
Secretions of the pancreas
Insulin; glucagon; digestive enzymes
Location of the pancreas
behind/beneath stomach; head resting in curve of duodenum; tip extending across the abodminal cavity to almost touch the spleen
Vascular supply of the pancreas
supplied by superior mesenteric and celiac trunk
Size of kidneys
>1 million nephrons per kidney
Function of kidneys
excretory organs, remove water-soluble waste;
Secretions of the kidneys
endocrine gland (produces renin - controls aldosterone secretion); primary source of erythropoietin; produces biologically active form of vit. D
Location of the kidneys
retroperitoneal space of upper abd; imbedded in fat/fascia; at T12-13; costovertebral angle formed by lower border 12th rib/transverse process of upper lumbar vertebrae; right sits slightly lower than left;
Vascular supply of the kidneys
1/8 cardiac output designated to kidneys via renal artery;
Function of ureters
carry urine to bladder from kidneys via peristolic waves
Vascular supply of the ureters
supplied by renal artery, aorta, gonadal (testicular or ovarian), common iliac, inf. Vesical, superior vesical arteries

indigestion
distress associated with eating; characterized by sense of: fullness, heartburn, discomfort, excessive belching, flatulence, lack of appetite, severe pain; location: localized/general, radiates to arms or shoulders; associated with: food intake, timing of food intake, amount, type; onset of s/sx: day or night, time, sudden vs. gradual; alleviate: meds: Rx or OTC

What is retching?
retching: “heaving,” spasmodic movements of chest and diaphragm that force gastric and/or duodenal contents into esophagus but not into pharynx; may proceed vomiting if upper esophageal sphincter (UES) remains closed; if UES is open vomiting occurs; usually caused by a bad smell or chocking
What is regurgitation?
regurgitation: controlled return or flow of stomach contents back into esophagus or mouth; usually without N/V or retching; occurs in GERD, esophageal stricture, and esophageal cancer
