● The front is through the mouth (rima oris)

● The back is through the oropharynx through the waist (isthmus faucium)

● The side walls are the cheeks and lips

● The upper is the hard and the soft palate

● The lower or the base of the mouth is the lower jaw bone, the tongue and the sublingual area

• the intersection of the

respiratory tract and gastrointestinal tract

goes from the base of the skull

to the lower margin of the ring cartilage.

● runs behind the larynx and

trachea, close to the spine, through the chest cavity, through the diaphragm to the connection with the stomach

● Connecting the esophagus and

duodenum, located just below the left diaphragmatic arch, behind the flank and left epigastric region.

● Tunica serosa: gastric lining

● muscle layer : vertical layer, ring layer, cross fiber

● Layer submucosa : there are many blood vessels and nerves, the association is very loose, so it is easy to push

● The lining of the mucosa : lining the inner wall of the stomach

If needed, the small intestine can be removed 3.5m

● The duodenum bends like a C and divided into 4 parts

+Upper +Down +The transverse part +The up

● SIZE: 1.4-1.8m long,

equal to ¼ length of small intestine, 7 cm in diameter, tapering to the sigmoid colon, bulging in the rectum bulging into a balloon

● Vessels and nerves

● Papillae and taste buds

● Frenulum

● 8-12 surrounding papillae

● V -shape

● in the upper layer of the transverse jejunum, in the right lower cell but encroach on the epigastric cell and the lower left diaphragm

STRUCTURE

● composed of the liver sac, liver tissue, many blood vessels and
