ABDOMEN Flashcards
Main Function of the GastroIntestinal System
Supply nutrients to body cells
GI system consists of the GI tract and its associated organs and glands:
(GI tract) Mouth, esophagus, stomach, small intestine, large intestines, rectum, anus
(Associated organs) Liver, Gall bladder, pancreas
Process of Digestion and Elimination:
Ingestion, Digestion, Absorption, Elimination
Food is broken down into small and simple compounds enough to be absorbed into bloodstream by ___ or ____
diffusion ; active transport
Effects of Aging on the GI Tract:
- Teeth may loosen up from the supporting gums and bones
- Decreased output of the salivary glands leads to dryness of mucous membranes and increased susceptibility to breakdown, difficulty swallowing and decreased stimulation of the taste buds
- Decreased secretion of digestive enzymes and bile– decrease ability to digest and absorb food. (Unpaired absorption of fat and fat soluble vitamins)
- Atrophy of gastric mucosa leads to decrease HCl acid production (Decrease iron and B12 absorption; anemia ;Proliferation of bacteria– diarrhea and infection)
- Decrease peristalsis in the large intestine, decrease muscular tone of the intestinal wall and decrease abdominal muscle strength, decrease sensation to defecate and increase incidence of constipation.
Regions of the Abdomen:
Epigastric, Umbilical, Suprabic or Hypogastric
Area between costal margin
Epigastric
Area around the umbilicus

Right Upper Quadrant (RUQ)
Liver, Gall bladder, Duodenum, Right Kidney, and Hepatic Flexure Colon
Left Upper Quadrant (LUQ)
Stomach, Spleen, Left Lobe of liver, Body of Pancreas, Left Kidney and Adrenal, Splenic Flexure of colon, Part of transverse and descending colon
Right Lower Quadrant (RLQ)
Cecum, Appendix (in female: right ovary, & right ureter)
Left Lower Quadrant (LLQ)
Part of descending colon, Sigmoid colon, Left ovary and tube, Left ureter, Left Spermatic cord
Midline:
Aorta, Uterus, Bladder
“Inspiratory arrest” palpating the liver should be painless but if pain is present; patient can’t complete deep breathing = cholecystitis
