The tongue is the organ for taste. The papillae contain the taste buds. The tongue is attached to the hyoid bone, mandible, styloid process, palate, floor of the mouth, pharynx, and epiglottis.

The tonsils are masses of lymphoid tissue at the base of the tongue. The epiglottis is cartilagenous tissue that separates the esophagus from the larynx and trachea. The roof of the mouth is the palate. The uvula closes off the nasopharynx during swallowing. 

The stomach has two openings. The upper is surrounded by the esophageal (cardiac) sphincter, and the lower by the pyloric schincter. These sphincters open and close, allowing food to enter and exit the stomach. The rugae are the folds of mucous membrane on the surface of the stomach.

The esophagus is a tube that transports food from the mouth to the stomach. At the distal end of the esophagus is the esophgeal (cardiac) sphincter. The duodedum is the first part of the small intestine and works to absorb nutrients. The pyloric sphincter opens to empty food into the duodenum. The ileum ends at the ileocecal valve, a sphincter that controls entry into the colon. The colon stores waste products until the anal sphincter opens to allow defecation. 

The liver is the largest organ in the body. It is roughly triangular, with a smooth brown surface. The liver receives arterial blood through the hepatic artery, venous blood leaves through the hepatic vein, and a third circulatory system, the portal, receives nutrient-rich blood from the gastro-intestinal tract. The liver works to detoxify substances in this blood.

The gallbladder stores bile, which is formed in the liver. Bile is used to digest fatty foods. The pancreas is wedge-shaped and secretes digestive enzymes and hormones. The parotid gland is located inferior and anterior to the ear. This gland secretes saliva. The adenoids are prominences of lymphoid tissue located in the nasopharynx. 

The gallbladder is a sac-like structure that contains bile. Bile is produced by the liver and transported to the gallbladder through the hepatic duct. The gallbladder is located on the posterior of the liver.

The pancreas is wedge-shaped and located located posterior to the stomach. The cecum is a pouch at the beginning of the colon. The appendix is attached to the cecum. The term "bursa" refers to a sac or cavity found in the vicinity of joints. The peritoneum is the membrane lining the abdominal cavity and enclosing the digestive organs. 

There is no superior lobe of the liver. There are four lobes and they are named as follows: quadrate, caudate, left, and right.

The esophagus enters the abdomen by piercing the diaphragm at the T10 vertebrae level. The esophagus is a muscular hollow tube that connects the pharynx with the stomach. It runs behind the trachea and heart and is located in front of the spine.

Except for the liver, all of the organs are retroperitoneal since they lie behind or are retro to the visceral peritoneum. The liver is an intraperitoneal organ. Intraperitoneal organs are moveable because they are completely surrounded by a visceral membrane. This membrane is known as a mesentery. The opposite of intraperitoneal organs are retroperitoneal organs, meaning they only have peritoneum located on the anterior side of the organ and cannot move.

The small intestine is divided into 3 parts, duodenum, jejunum, and ileum. The duodenum is the first part, and thus receives bile from the liver and gallbladder and digestive enzymes from the pancreas. The jejunum is the location of the small intestine where most of the digestion and absorption occurs.

The falciform ligament divides the liver into a right and left lobe. The round ligament is the inferior part of falciform ligament that is thick and round. The coronary ligament, caudate lobe, and quadrate lobe are all found on the posterior side of the liver, while the falciform ligament is found on the anterior side. 

Intraperitoneal organs are moveable because they are completely surrounded by a visceral membrane. This membrane is known as a mesentery. Examples of these organs include the stomach and the liver. The opposite of intraperitoneal organs are retroperitoneal organs. This means that the organs only have peritoneum located on their anterior side. All of the listed answer choices other than stomach and liver are retroperitoneal organs because they are not moveable and only have peritoneum lining the ventral side.
