Components

(generated)

• Component items*:
• *Stomach sensory data* (*stomach-sensory-data*)

* Stomach - stomach nutrition sensor (stomach-nutrition-sensor -> LPC.PN.SG.LDRG): sense independently to tongue and oral taste receptors glucose, carbohydrates proteins, and fats

• *Stomach gastrointestinal tract* (*stomach-gastrointestinal-tract*)

* [- outer longitudinal and inner circular smooth muscles] (BrainRegionLAC_PN_PSYM_PPG LAC.PN.PSYM.PPG -> HumanMusclesTorso stomach-wall): acetylcholine activates muscarinic receptors on smooth muscles - increasing motility of the stomach
* [- mucosal gastric glands] (BrainRegionLAC_PN_PSYM_GUT LAC.PN.PSYM.GUT -> HumanMusclesTorso stomach-mucosal-gastric-glands): acetylcholine activates muscarinic receptors cause an increase in gastric juice secretion
* Stomach - enzyme glands (stomach -> LPC.PN.SG.NOD): secretes protein-digesting enzymes called proteases and strong acids to aid in food digestion; digestion; nutrition sensor; some absorption
* Stomach - small intestine (small-intestine -> LPC.PN.SG.NOD): where most chemical digestion takes place; food from stomach is allowed into duodenum through pylorus by pyloric sphincter; absorb nutrients from ingested food
* Stomach - duodentum (duodentum -> LPC.PN.SG.NOD): food intake regulation, via glucoreception in taste receptors
* Stomach - colon (colon -> LPC.PN.SG.NOD): extracts water and salt from solid wastes; storing waste

• *Stomach extractors* (*stomach-extractors*)

* Stomach - spleen (spleen -> LPC.PN.SG.NOD): red pulp - blood filter, removes old red blood cells, holds a reserve of blood, recycles iron; white pulp - synthesizes antibodies in its white pulp and removes antibody-coated bacteria and antibody-coated blood cells by way of blood and lymph node circulation
* Stomach - kidney (kidney -> LPC.PN.SG.NOD): regulating acid-base balance, electrolyte concentrations, extracellular fluid volume, blood pressure, filter to urine
