UBERON:0007365 ·resolve ·HOST_ASSOCIATED ·EXACT REVIEWED

The first compartment of the ruminant stomach. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. — UBERON

Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

GROUND 2026-08-21 · codex-gpt-5
Grounded to UBERON:0007365 'rumen' (CLOSE). Definitions-from-research follow-up (#110): the committed report shows that Madin's host_animal_endotherm_rumen bin denotes the rumen and its sampled contents, and UBERON:0007365 names the ruminant anatomical compartment. CLOSE records that bin-versus-compartment framing difference. Grounding merges 132 Madin taxon assertions into the existing reviewed rumen record while retaining the HOST_ASSOCIATED override. (source concept habitatmech:BACDIVE.ed51f3e74a)
GROUND 2026-08-21 · codex-gpt-5
Grounded to UBERON:0007365 'rumen' (EXACT). Adversarial review follow-up (#172): PREGO's BTO:0001194 rumen and UBERON:0007365 both name the first ruminant stomach compartment. The BTO definition adds its microbial fermentation function but does not define a different habitat. Grounding PREGO to the already reviewed UBERON anatomy identity consolidates 231 PREGO taxon assertions with the Madin rumen evidence added for #110; the BTO source identifier remains explicit in the attestation.
