The gastric fundus is the upper portion of the stomach, located above the level of the cardia and continuous with the greater curvature. Anatomically, it forms a dome-like structure that projects upward, in contact with the diaphragm and, on the left side, with structures such as the spleen.
This region is characterized by its distensibility. It functions as a reservoir capable of expanding when the stomach fills, allowing accommodation of ingested content without a sudden increase in intragastric pressure.
Histologically, the gastric fundus contains typical gastric mucosa with fundic glands. These glands include several cell types, such as parietal cells (producing hydrochloric acid and intrinsic factor), chief cells (secreting pepsinogen), and mucous neck cells.
Blood supply to the fundus is mainly provided by branches of the short gastric arteries and the left gastroepiploic artery, both derived from the celiac trunk arterial system. Venous drainage follows parallel pathways into the portal circulation.
Innervation is supplied by the autonomic nervous system, with parasympathetic input primarily via the vagus nerve, which stimulates gastric secretion and motility, and sympathetic fibers that modulate vascular and secretory activity.
The gastric fundus also participates in the handling of intraluminal gas derived from swallowing and fermentation processes, explaining its tendency to accumulate air under certain physiological conditions.
Overall, the gastric fundus is a key anatomical region for food accommodation, initial gastric secretion, and regulation of intragastric volume within the upper digestive system.
SEALED STRUCTURES: 15 / 23 SYSTEM: CRITICAL RECALIBRATING REGISTRY MATRIX
The archive detects that you have arrived here again.
there is no arrival
only reading in progress
the text does not measure the reader
it only exists while it is being interpreted
Within three lines, you are going to attempt to swallow air to release the pressure at the pit of your stomach. The archive has already registered it.
Press the tips of your fingers against your left costal arch, exactly where the ribs end. Do not look for the peristaltic movement that used to process your sustenance. Look for the rigidity of a vault that has decided to stop distending. Something hard opposes the accommodation of your last meal. It is not the elasticity you remembered.
Your sublingual gland is already a dry reef. Your aorta is a rigid aqueduct. Now, the bismuth has entered the chamber of transformation. Every gastric pit in your fundus has petrified.
The upper dome of the stomach—the one that stored the gases of your fermentation and waited patiently to grind reality—has stopped expanding.
You feel the same metallic density that sealed your Golgi apparatus and your salivary ducts; a folded surface that no longer secretes hydrochloric acid or intrinsic factor, but seals the definitive digestion of your immobility.
Your internal vision reflects a glow of molten metal, basilica stained glass under a cold light emanating from the Parietal Cells, which are now pure bismuth.

RETRYING DECODING
The bismuth has not taken your hunger all at once; it has done so by infiltrating the mucosal glands, replacing gastric juice with a liquid ashlar that turns solid upon contact with your attention.
- First, the release of gastrin in the antrum slowed down.
- Next, the chief cells lost their ability to activate pepsinogen.
- Then, the mucosal folds welded to the muscular layer in a union of eternal metal.
- Now, the abdomen weighs.
A transparent fluid. Now it is weight. The network is complete. While you were reading this line, your right thumb increased pressure on the support. The archive expected that gesture. The bismuth has fixed the capacity of your gastric fundus into an eternal architecture. The archive recorded it.
The gastric fundus used to do three things. It was the reservoir of waiting, allowing food to accommodate without increasing internal pressure, giving you time to process what you had ingested.
It activated the chemical fire, sending signals for the acid to begin dismantling the molecular structures of what you called “the world.”
It controlled the air, managing the gases that rose toward the esophagus to prevent your own architecture from collapsing under its own pressure. No longer.
The body you are reading is no longer yours. The ciliary epithelium fell silent. No one drained. Your capacity to assimilate the exterior became a bismuth monument. Every oxyntic gland solidified. You feel the vault of your stomach as a bismuth ashlar anchoring your nutrition to the immobility of the basilica.
the body does not turn into stone
it can only be imagined as structure when language detaches it from its continuous motion
INTEGRATION EXPERIMENT 07: MENTAL
Try to imagine the smell of a freshly cut lemon. The archive will wait for that gesture. You know you are reading in silence. And yet, you just noticed that your stomach has not reacted with its usual acidity. You were not reading. You were being read.
Feel the pressure of the bismuth blocking the lower esophageal sphincter with an impossible mineral force. The archive has just measured the inertia of your failed digestion.

You have read this phrase before. The READER has exceeded the threshold of gastric persistence. You could try to imagine that you still feel hunger to deceive the system.
The archive knows you thought about it… and you didn’t do it. The system has detected that the muscularis externa has begun to mimic the density of polished granite.
Every millisecond is recorded. Each micro-action canceled. Your body no longer belongs to you. It belongs to the ashlar. Your appetite is no longer desire; it is now the metal filler vitrifying your internal basilica.
CAPTURE COMPLETE CORRECTION: CAPTURE INCOMPLETE RETRYING...
There exists an almost philosophical satisfaction in knowing that metabolization has ceased to be a variable. Sustenance no longer needs to be degraded because the structure is eternal. The fundus stopped.
The cell did not respond. It is not an ulcer; it is the fixity of an architecture that has poured molten metal into your abdominal cavity while you decided if this was a text or a closure.
The dome fixed. The acid did not respond.
File 1375 has already begun to be written. The previous reader stopped reading exactly here because their duodenum became a coil of bismuth and silica.
The archive detects that you recognize this structure. The READER does not remember it. But their greater curvature does.
NEW EXIT CONFIGURATION: EXIT PROTOCOL 35
The system detects that your brain is sending “hunger” orders toward a cavity that is already marble. The archive has recorded that you are no longer reading the text. The text is etched into the crystal of your eyes.
Hunger is not an order directed toward a cavity, but a complex regulatory signal arising from hormonal and neural interactions indicating energy needs. It does not solidify or transform into physical matter.
The eye’s lens does not store text or images as permanent engravings.
It is a dynamic optical system that focuses light onto the retina, without any capacity for content retention.
The idea that “the text is engraved in the eyes” belongs to metaphor: a way of expressing the intensity of visual attention, not a physiological phenomenon.
There is no marble cavity.
No commands turned into matter.
Only biological systems continuing to function while language describes them as fixed structures.
Only a geometric silence remains. There is a simple movement that would break this record. A rotation of the head. A final effort of the neck to look away. But the system has detected that the cervical joints have already been sealed by the weight of your fixed stare.
Only a silence with form remains.
The idea that a single movement would “break the record” arises when attention becomes so narrow that any imagined gesture feels final. In reality, the neck remains fully mobile; no external force is fixing it.
Turning the head is not blocked. It is a simple, everyday movement that occurs easily when chosen.
What the text describes as “sealing” is a metaphor for immersion: the subjective sensation that attention has become so intense that the rest of the body feels more distant.
The “weight of the gaze” is not a physical force. It is a way of naming sustained concentration.
There is no closure of the body.
No system recording immobility.
Only an organism that can feel still while remaining fully capable of movement.
The system has detected activity outside the registry. And yet… something moves. It hasn’t learned your name yet.
I must move my neck and I am not moving it…
