peritoneum
transparent membrane lining the inside of the posterior body cavity
serous membrane, secretes lubricating fluid
serous membrane
secretes lubricating fluid
peritoneal cavity
posterior cavity in mammals and amphibians
thoracic cavity
most anterior cavity in mammals and amphibians
pericardial cavity
sharks anterior cavity
AND
the portion of a mammal/amphibians thoracic cavity surrounding the heart
pleural cavity
paired lateral cavities in mammals and amphibians surrounding the lungs (part of the thoracic cavity)
pleuroperitoneal cavity
sharks posterior body cavity
transverse septum
tough white membrane separating the sharks pericardial cavidy and pleuroperitoneal cavity
diaphragm
muscular structure separating the anterior and posterior cavities
fat bodies
buccal cavity
pharynx
just posterior to buccal cavity, identified by 5 pairs of gill slits
esophagus
stomach
rugae
longitudinal folds in the stomach
small intestine
duodenum
most anterior portion of the small intestine in the shark
ileum
posterior portion of the small intestine in the shark
large intestine
pancreas
accessory organ, from endoderm
evagination of the embryonic digestive tract
in shark - 2 lobes (ventral in the curve of the duodenum, dorsal in a ligament that projects towards the gastrosplenic ligament
liver
accessory organ, from endoderm
evagination of the embryonic digestive tract
in the shark - 3 lobes
extends posteriorly from the transverse septum
gallbladder
accessory organ, from endoderm
evagination of the embryonic digestive tract
greenish and located on the central love of the liver in sharks
bile duct
leads from the gallbladder to the duodenum
cardiac sphincter
where the esophagus ends, opens into the stomach
pyloric sphincter
sphincter at the most posterior end of the stomach
