Concepts of Structures and FunctionsThe GI System consists of the GI tract and its associated organs and glands
A. GI tract
1. mouth
2. esophagus
3. stomach
4. small intestines
5. large intestines
6. rectum
7. anus
B. Associated organs
1. liver
2. gall bladder
3. pancreas

Structures and Function of the GastroIntestinal System
Main Function of the GI System?????
Supply Nutrients to body cells

Process of Digestion and Elimination
A. Ingestion ( Taking In Food)
B. Digestion ( Breakdown of Food)
C. Absorption ( transfer of food products into the circulation)
D. Elimination
![Page 8: abdominal assessment](https://reader033.vdocuments.us/reader033/viewer/2022042817/55a5e01e1a28ab7e558b4823/html5/thumbnails/8.jpg)
Digestion and AbsorptionFood is broken down into small and simple
compounds enough to be absorbed into the bloodstream by diffusion or active
transport.
![Page 9: abdominal assessment](https://reader033.vdocuments.us/reader033/viewer/2022042817/55a5e01e1a28ab7e558b4823/html5/thumbnails/9.jpg)
Effects of Aging on the Gastrointestinal TractA. Teeth may loosen up from the supporting gums and bones.B. Decreased output of the salivary glands leads to dryness of mucous
membranes and increased susceptibility to breakdown, difficulty swallowing and decrease stimulation of the taste buds.
C. Decreased secretion of digestive enzymes and bile – decrease ability to digest and absorb food.
>> impaired absorption of fat and fat soluble vitamins D. Atrophy of gastric mucosa leads to decrease HCl acid production.
>>decrease iron and B12 absorption – anemia>>proliferation of bacteria – diarrhea and infection
E. 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.

Auscultation for bowel sounds
• Normal sounds are due to
peristaltic activity
5- 30 time \min.• peristalsis: A progressive
high pitched gurgeling,cascading sound sound begin with RLQ.

Bowel sound abnormalities
• Hyperactive sound :
• Auscultate peristaltic sounds which are normally loud, high pitched
• Hypoactive sound : less than 5 time \min
• Silent abdomen : listen for at least "5" minutes before concluding that no bowel sound (. In case of abdominal surgery,inflammation

Cont –Kidneys
• Search for right kidney by placing your hands together in a “duck-bill” position at person’s right flank
• Press your two hands together firmly (you need deeper palpation than that used with the liver or spleen) and ask person to take deep breath
• In most people, you will feel no change• Occasionally, you may feel lower pole of right
kidney as a round, smooth mass slide between your fingers
![Page 68: abdominal assessment](https://reader033.vdocuments.us/reader033/viewer/2022042817/55a5e01e1a28ab7e558b4823/html5/thumbnails/68.jpg)
Cont
• Left kidney sits 1 cm higher than right kidney and is not palpable normally
• Search for it by reaching your left hand across abdomen and behind left flank for support
• Push your right hand deep into abdomen and ask person to breathe deeply
• You should feel no change with inhalation
![Page 69: abdominal assessment](https://reader033.vdocuments.us/reader033/viewer/2022042817/55a5e01e1a28ab7e558b4823/html5/thumbnails/69.jpg)

PERCUSSION
Determine the presence of fluid, distention, and masses. Presence of air – tymphany,
•Assessment technique used to assess size and density of organs in the abdomen
•Examples: used to measure size of liver or spleen
• lightly percussing all 4 quadrants for tympany or dullness
• tympany usually predominates due to gas in the bowel

ii) Guarding: This is an involuntary reflex contraction of the muscles of the abdominal wall overlying an inflamed
viscus and peritoneum. It produces local rigidity and indicates localised peritonitis. The spasms of the muscle will prevent palpation of the underlying viscus. Guarding is seen for example in acute appendicitis

Example: Typical pain in Acute appendicitis
Site: poorly localized, periumbilical pain followed usually by RLQ pain
Onset: vagueCharacter: dull periumbilical pain, may be crampingRadiation: periumbilical RLQAssociated factors: anorexia, nausea/vomiting, low feverTiming: Periumbilical (4-6h), RLQ (depends on
intervention)Exacerbating/relieving factors: if subsides temporarily,
suspect perforation of the appendix, movement/cough.Severity: periumbilical (mild but increasing), RUQ
(steady/more severe)
