What is the uvula?
This is the name of the longitudinal folds founds inside the stomach
What are rugae?
This section of the small intestine is neither the shortest nor the longest, however it is where the majority of nutrient absorption occurs.
What is the jejunum?
The large intestine is primarily responsible for the absorption of water and these
What are electrolytes?
These are the four accessory organs of the digestive system.
What are the salivary glands, the liver, the gallbladder, and the pancreas?
The parotid, submandibular, and sublingual glands produce this substance.
What is saliva?
This is the term for the mixture of food and gastric juices that leaves the stomach and travels into the small intestine.
What is chyme?
These three features increase the absorptive surface area of the small intestine.
What are plicae circulares, villi, and microvilli?
Of the six functions of the digestive system, the large intestine is involved in these two.
What are absorption and elimination of waste products?
Bile is produced by the liver, then stored and concentrated in this organ.
What is the gallbladder?
Found anterior and inferior to the ear, this is the largest of the salivary glands.
What is the parotid gland?

What are goblet cells?
This feature gives the large intestine its "pouchy" appearance.

These longitudinal bands on the large intestine allow for contractions which move stool through along the large intestine.
What are taeniae coli?
The pancreas secretes enzymes to aid in digestion. Pancreatic amylase acts on starches, peptidase acts on peptides, lipase acts on lipids, and this, which acts on proteins.
What is trypsin?
