Gastrointestinal Tract (GI Tract) |
• AKA- Alimentary Canal or Digestive Tract or “Gut” • organs that take in food, digest it to extract energy/nutrients and expels the remaining waste • organs in this system contained within the Peritoneum • large hollow organs of the GI tract contain muscle that enable walls to move
|
|
|
|
Peritoneum |
A serous membrane that forms the lining of the abdominal cavity |
|
|
|
Peristalsis |
Movement of the organ walls which moves the food along in a wavelike action |
|
|
|
Upper GI Tract |
• Mouth • Pharynx • Esophagus • Stomach |
MPES Acronym |
|
|
Mouth |
Beginning of canal & initiation of mechanical breakdown of food |
|
|
|
Pharynx |
Fibromuscular part of canal where swallowing takes place. *this word denotes “opening” in this portion of human anatomy. |
|
|
|
Esophagus |
Moves the bolus along to the stomach by peristaltic muscular contractions |
|
|
|
Stomach |
Food bolus is treated to mechanical and chemical digestion. |
|
|
|
Lower GI tract |
• small intestine • large intestine |
|
|
|
Small intestine |
Additional enzymatic and mechanical digestion. Lining absorbs nutrients of molecular size and capillaries deliver to liver for processing • duodenum • jejunum • Ileum |
|
|
|
Large intestine |
Absorbs minerals and water; Storage and discharge • Cecum • Colon- ascending, transverse, descending & sigmoid flexures • rectum • Anus |
|
|
|

|
|
|
Salivary glands |
Softens and partly digests ingested food |
|
|
|
Liver |
Produces and discharges bile to breakdown fats; processes molecular nutrients |
|
|
|
Gallbladder |
Stores bile |
|
|
|
Bile duct |
Discharges bile from gallbladder into the duo duodenum |
|
|
|
Pancreas |

|
Peritoneum |
Parietal peritoneum Visceral peritoneum Peritoneal cavity Mesenteries Omenta |
PVPMO Acronym |
|
|
Parietal peritoneum |
The outer layer attached to the abdominal wall |
|
|
|
Visceral peritoneum |
The inner layer wrapped around the internal organs that are located inside the abdominal cavity |
|
|
|
Peritoneal cavity |
The space between these two layers; it is filled with a small amount (about 50 ml) of slippery serous fluid that allows the two layers to slide freely over each other |
|
|
|
Mesenteries |
Peritoneal layers suspending organs |
|
|
|
Omenta |
Peritoneal layers suspending an organ from another organ; Ligaments |
