ASSESSMENT OF ABDOMEN Flashcards
System responsible for digesting the food that we eat
Gastrointestinal System or GI System
Components of the GI System
- Mouth
- Tongue
- Parotid, sublingual, and sub-mandibular glands
- Epiglottis
- Pharynx
- Esophagus
- Stomach
- Rugae
- Small Intestine
- Vermiform Appendix
- Large Intestine
Identify which component of GI System is being described
- this is where the first step of digestion occurs
- chewing, salivating, and swallowing
Mouth
Identify which component of GI System is being described
- Provides sense of taste
Tongue
Identify which component of GI System is being described
- they produce saliva
Parotid, Sublingual, and Submandibular glands
Identify which component of GI System is being described
- keeps food and fluid from being aspirated into the airway by closing over the larynx when food is swallowed
Epiglottis
Identify which component of GI System is being described
- consists of nasopharynx, oropharynx, and laryngopharynx
- allows passage of food from mouth to the esophagus
- assist in swallowing
- secretes mucus which aids in digestion
Pharynx
Identify which component of GI System is being described
- hollow, muscular tube that is approximately 10 in long
- moves food from the pharynx to the stomach using peristalsis
Esophagus
Identify which component of GI System is being described
- dilated sac like structure that lies obliquely in the left upper quadrant
- contains two important sphincters: the cardiac sphincter and the pyloric sphincter
- stores food and mixes it with gastric juices
- passes chyme into the small intestine for further digestion and absorbtion
Stomach
This sphincter protects the entrance to the stomach
Cardiac Sphincter
This Sphincter guards the exit of the stomach
pyloric sphincter
Identify which component of GI System is being described
- accordion like folds in the stomach lining
- allow stomach to expand
Rugae
Identify which component of GI System is being described
- consist of the duodenum, jejunum, and ileum
- location of carbohydrate, fat, and protein breakdown
- absorbs the end products of digestion
Small Intestine
Identify which component of GI System is being described
- finger like projection attached to the cecum
Vermiform Appendix
Identify which component of GI System is being described
- consists of the cecum; ascending, transverse, descending, and sigmoid colons; rectum; anus
- absorbs excess water and electrolytes
- stores food residue
- eliminates waste products in the form of feces
Large Intestine
This junction normally remains closed to prevent reflux of gastric contents and only opens during swallowing, belching, and vomiting
Esophagogastric Junction
Acessory GI organs and vessels
- Liver
- Gallbladder
- Pancreas
- Bile Ducts
Identify the Acessory GI organs or vessels being described
- metabolizes carbohydrates, fats, and proteins
- detoxifies blood
- converts ammonia to urea for excretion
- synthesizes plasma proteins, nonessential amino acids, vitamins, and essential nutrients
- secretes bile to digest fats and absorb fatty acids, cholesterol, and other lipids. It also gives stool their color
Liver
Identify the Acessory GI organs or vessels being described
- Stores bile from the liver until the bile empties into the duodenum
Gallbladder
Identify the Acessory GI organs or vessels being described
- measures 6 to 8 inches
- consist of a head, body, and tail
- releases insulin and glycogen into the bloodstream and produces enzymes that aid in digestion
Pancreas
Identify the Acessory GI organs or vessels being described
- has hepatic duct, cystic duct and common bile ducts
Bile Ducts
This duct drains bile from the liver
Hepatic Duct
This duct drains bile from the gallbladder
Cystic Duct
