Your stomach is not a passive acid bag. It is a muscular holding chamber that stores food, churns it with acid and enzymes, and releases partly digested chyme into the small intestine in small batches. 1
Swipe through today's 4 cards:
- The big idea: acid bath + muscle churn.
- The map: cardia, fundus, body, antrum, pylorus, rugae, mucosa, and gastric glands. 2
- Why it matters: the stomach can digest food without digesting itself because surface mucus cells help protect the stomach wall from its acidic environment. 3
- Today's exercise: take one small bite, chew until soft, swallow, then notice how fullness begins before food ever reaches your intestines.
Skip the exercise if eating feels uncomfortable today. This post is for learning, not diagnosis; persistent pain, vomiting, bleeding, or trouble eating should be checked by a clinician.
