Assessment of Abdomen Flashcards
Begins digestion through chewing, salivating, and swallowing
Mouth
Provides sense of taste
Tongue
Saliva is produced by three pairs of glands:
parotid, submandibular, and sublingual
Keeps food and fluid from being aspirated into the airway (trachea) by closing over the larynx when food is swallowed
Epiglottis
Pharynx consists of the
nasopharynx, oropharynx, and laryngopharynx
Allows the passage of food from the mouth to the esophagus
Pharynx
■ Assists in swallowing
■ Secretes mucus, which aids digestion
Pharynx
Hollow, muscular tube that’s approximately 10” (25.5 cm) long
Esophagus
Esophagus is a hollow, muscular tube that’s approximately _________________ long
10” (25.5 cm)
Moves food from the pharynx to the stomach using peristalsis
Esophagus
Dilated, saclike structure that lies obliquely in the left upper quadrant
Stomach
Stomach contains two important sphincters:
cardiac sphincter and pyloric sphincter
protects the entrance to the stomach
cardiac sphincter
guards the exit
pyloric sphincter
Stores food and mixes it with gastric juices
Stomach
Passes chyme into the small intestine for further digestion and absorption
Stomach
Accordion-like folds in the stomach lining
Rugae
Allow stomach to expand
Rugae
Small intestine consists of the
duodenum, jejunum, and ileum
Location of carbohydrate, fat, and protein breakdown
Small intestine
Absorbs the end products of digestion
Small intestine
Fingerlike projection that’s attached to the cecum
Vermiform appendix
Large intestine consists of the
cecum; ascending, transverse, descending, and sigmoid colons; rectum; and anus
- Absorbs excess water and electrolytes
- Stores food residu
Large intestine
Eliminates waste products in the form of feces
Large intestine
■ Metabolizes carbohydrates, fats, and proteins
■ Detoxifies blood
■ Converts ammonia to urea for excretion
Liver
Synthesizes plasma proteins, nonessential amino acids, vitamins, and essential nutrients
Liver
Secretes bile
Liver
a greenish fluid that helps digest fats and absorb fatty acids,
cholesterol, and other lipids and gives stools their color
bile
Stores bile from the liver until the bile empties into the duodenum
Gallbladder
drain bile from the liver
Hepatic ducts
drains bile from the gallbladder
Cystic duct
receives bile from the hepatic and cystic ducts and empties bile into the duodenum
Common bile duct
Releases insulin and glycogen into the bloodstream and produces enzymes that aid in digestion
Pancreas
