5 & 6 Digestive System Flashcards

Throat, the common pathway for food from the mouth and for air from the nose.
Pharynx
Large vein bringing blood to the liver from the intestines
Portal vein
Enzyme that digests proteins
Protease
Soft tissue within the teeth containing nerves and blood vessels.
Pulp
Ring of muscle at the end of the stomach, near the duodenum.
Pyloric sphincter
Distal region of the stomach, opening to the duodenum.
Pylorus
Last section of the large intestine, connecting the end of the colon to the anus.
Rectum
Ridges on the hard palate and the wall of the stomach.
Rugae
Digestive juice containing amylase produced by salivary glands.
Saliva
Parotid, sublingual and submandibular glands
Salivary glands
Lower S shaped segment of colon, just before the rectum; empties into the rectum.
Sigmoid colon
Circular ring of muscle that constricts a passage or closes a natural opening
Sphincter
Muscular organ that receives food from the esophagus.
Stomach
Fat molecules composed of three parts fatty acids and one part glycerol.
Triglycerides
Soft tissue hanging from the middle of the soft palate.
