Chapter 3 Flashcards
(155 cards)
These acute or emergency conditions require what is commonly referred to as an “__” wherein several abdominal images are performed in different positions to demonstrate air-fluid levels, free air, or both within the abdominal cavity.
acute abdominal series,
Typically, a __ are performed to complete the acute abdominal series
supine KUB, an upright AP or decubitus abdomen, and a PA or AP chest
The___ must be perfectly motionless during imaging of the abdomen or the chest.
diaphragm
The most important in abdominal radiography are the
right and left hemidiaphragms and the right and left psoas (so-es) major
The six organs of the digestive system are as follows:
- Oral cavity
- Pharynx
- Esophagus
- Stomach
- Small intestine
- Large intestine
The three digestive organs within the abdominal cavity are the
stomach and small and large intestines
The __ is the first organ of the digestive system located entirely within the abdominal cavity.
stomach
The __ continues from the stomach as a long, tubelike convoluted structure about 15 to 18 feet (4.5
to 5.5 m in length.
small intestine
The small intestine’s three parts are labeled in descending order in are as follows:
duodenum (doo-o-de-num) (A); jejunum (ie-joo-num) (B); and ileum (il-eum) (C).
The first portion of the small intestine, the __, is the shortest and widest, in diameter of the three seg-ments. It is about 10 inches (25 cm) in length.
duo-denum
Ducts from the __ drain into the duodenum to aid digestive functions.
liver, gallblad-der, and pancreas
The first two-fifths, following the duodenum, are the __, and the distal three-fifths are the __.
jejunum ileum
The orifice (valve) between the distal ileum and the cecum portion of the large intestine is the
ileocecal valve
The sixth and last organ of digestion is the __, which begins in the right lower quadrant at the junction of the small intestine and the ileocecal valve.
large intestine
The portion of the large intestine below the ileocecal valve is a saclike portion named the __.
cecum
The __ is attached to the posteromedial aspect of the cecum
appendix (vermiform appendix)
The vertical portion of the large bowel, above the cecum, the __, joins the transverse colon at the right colic (kol-ik, referring to the colon) flexure.
ascending colon
The transverse colon joins the __ at the left colic flexure.
descending colon
Alternative secondary names for the two colic flexures are __, based on their proximity to the liver and spleen,
hepatic (right) and splenic (left) flexures
The descending colon continues as the __.
S-shaped sigmoid colon in the lower left abdomen
The __ is the final 6 inches (15 cm) of the large intestine.
rectum
The rectum ends at the __, the sphincter muscle at the terminal opening of the large
anus
shape and location of the large intestine varies greatly, with the transverse colon located _ in the abdomen of broad hypersthenic body types and __ in the abdomen of slender hyposthenic and asthenic body types
high , low
The spleen is the part of the __ that, along with the heart and blood vessels, is part of the circulatory system.
lymphatic system
