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)
  • Stomach - outer longitudinal and inner circular smooth muscles (LAC.PN.PSYM.PPG -> stomach-wall): acetylcholine activates muscarinic receptors on smooth muscles - increasing motility of the stomach
  • Stomach - mucosal gastric glands (LAC.PN.PSYM.GUT -> 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
