It is a structure of the pharynx. The triangular depressed area between the two arches is called the "tonsillar fossa", which contains the tonsils.
Inferior wall (floor of mouth)

oral cavity
The oral cavity is the beginning of the digestive tract. It communicates with the outside world through the cleft in the front, and continues with the pharynx through the pharynx in the back. There are teeth, tongue and other organs in the oral cavity. The front wall of the mouth is the lip, the side walls are the cheeks, the roof is the palate, and the floor of the mouth is the mucous membrane and muscles. "The oral cavity is divided into the anterolateral oral vestibule (oral vestibule) and the posterior and medial part of the oral cavity proper by the upper and lower dental arches"; when the upper and lower teeth are occluding, there is a gap between the oral vestibule and the proper oral cavity. Connected by the space behind the third molar. Clinically, when the patient has trismus, a mouth opener or intubation can be placed through this channel to inject drugs or nutrients while preventing tongue bite.

The left and right hepatic ducts exit the porta hepatis and form the common hepatic duct
common bile duct
The common hepatic duct descends and meets the cystic duct at an acute angle to form the common bile duct
Big question: The hepatopancreatic ampullary sphincter usually maintains a contracted state, allowing bile to enter the gallbladder for storage through the hepatic duct, common hepatic duct and cystic duct. (fasting) After eating, under the action of neurohumoral factors, the gallbladder contracts and the hepatopancreatic ampullae sphincter relaxes, allowing bile to pass from the gallbladder through the cystic duct and common bile duct into the duodenal cavity.

pleural cavity
The visceral pleura and parietal pleura continue with each other at the lung roots, forming a completely closed cavity around the left and right lungs.
The pressure inside is lower than the air pressure, so it is negative pressure. There is only a small amount of serous fluid in the cavity, which can reduce the friction between the viscera and parietal pleura during breathing.

A double-layered peritoneal structure that extends downward from the porta hepatis to the lesser curvature of the stomach and the upper part of the ampulla of the duodenum
branch
Hepatogastric ligament; connects between the porta hepatis and the lesser curvature of the stomach
Hepatoduodenal ligament; connects the porta hepatis to the upper part of the duodenum
mesangium
The double-layer peritoneal structure connected between the intestines and other organs and the posterior abdominal wall, pelvic wall, etc.
Mainly include; intestinal [empty, gyrus] mesentery, appendiceal mesosome, transverse colon mesosome, sigmoid mesocolon, and ovarian mesentery.

The tip of the renal pyramid merges into a renal papilla, which flows into the small renal calyces. The small renal calyces merge into the larger renal calyces, and the larger renal calyces merge into a funnel-shaped flat sac called the renal pelvis in the renal sinus.
The anterior and lower mucosa of the nasal septum has a rich plexus of blood vessels and is a common site for epistaxis. It is called the bleeding-prone area (Little area).
The common bile duct and pancreatic duct join to form the "hepatopancreatic ampulla": the common bile duct joins the "pancreatic duct" in the posteromedial wall of the middle part of the descending duodenum, forming a slightly enlarged common duct. Opens into the descending part of the duodenum (major papilla). The hepatopancreatic ampulla is surrounded by the hepatopancreatic ampulla sphincter (or sphincter of Oddi).
