Lab 8 Flashcards
The oral cavity
from the lips to the soft palate’s posterior limit, from the tongue to the hard palate, and from cheek to cheek
salivary gland function
saliva production
3 salivary glands
parotid, submandibular, and sublingual glands
upper passage of food/drink
oral cavity -> oropharynx -> layyngopharynx -> epiglottis closed -> esophagus -> stomach
number of teeth in adult
32 16 upper (maxillary) and 16 lower (mandibular)
quadrants of teeth (medial to lateral)
2 incisors, 1 canine, 2 premolars, 3 molars
deciduous teeth
baby teeth
all but the 3 sets of molars
abdominopelvic cavity quadrants
right upper, right lower, left upper, left lower
organs of the right upper quadrants of the abdominopelvic cavity
liver, gall bladder, ascending colon, right kidney
organs of the right lower quadrants of the abdominopelvic cavity
cecum, appendix
organs of the left upper quadrants of the abdominopelvic cavity
spleen, body of stomach, descending colon, left kidney, pancreas
organs of the left lower quadrants of the abdominopelvic cavity
sigmoid colon
The peritoneal cavity (perironeum)
membrane-bound space within the abdominopelvic cavity
divisions of the peritoneal membrane
visceral, parietal, mesentery
The visceral peritoneum
covers many digestive organs as they pass through the abdomen
The parietal peritoneum
forms the outer wall of the peritoneal cavity and, in many places, joins the body wall
The mesentery peritoneum
forms the connection between the parietal and visceral layers, allows passage of vessels and nerves between the layers of peritoneum
Greater omentum
extension of mesentery, layer of visceral fat that hangs from the stomach and covers the intestines
intraperitoneal organs definition
surrounded by the visceral peritoneum and the peritoneal cavity
intraperitoneal organs include
stomach, small intestine, liver, gallbladder
retroperitoneal organs definition
outside of or behind the peritoneum
retroperitoneal organs include
kidneys, ureters, parts of the large intestine, pelvic organs (uterus, urinary bladder)
chyme
food/drink mixed with gastric secretions in the stomach
rugae
folds of the gastric walls in the stomach, flatten out when the stomach is full
passage of food through the stomach
cardiac sphyincter -> cardia -> fundus -> body -> pylorus -> pyloric sphyincter -> duodenum
production site of bile
liver
passage of bile storage
liver -> hepatic duct -> cystic duct -> gallbladder
passage of bile usage
gallbladder -> cystic duct -> common bile duct -> duodenum
lobes of the liver
right, left, caudate, quadrate
portal triad definition
the vessels that enter/exit the liver
portal triad includes
hepatic artery, hepatic portal vein, and common bile duct
functions of the liver
- absoprtion: glucose, amino acids, iron, vitamins for storage or use of metabolism
- elimination: removal of toxins, bilirubin, drugs, from blood
- nutrient release: glucose, protein, lipids released on demand to meet the body’s needs
bile function
lipid digestion
pancreas function
- produce the hormones insulin and glucagon necessary for stabilizing blood glucose levels
- produce digestive enzymes (bicarbonate ions)
cells of the pancreas responsible for insulin and glucagon
pancreatic islets
passage of bicarbonate ions
pancreas -> pancreatic duct -> common bile duct -> duodenum
region of the abdomen that the pancreas is found
epigastric region
region of the abdomen that the spleen is found
left hypochondriac region
spleen function
immune function
passage through the small intenstine
duodenum -> jejunum -> ileum
