Start by locating the existing UBERON:0035763 entry, then compare the requested atrial and ventricular cavity terms with their listed synonyms, definitions, parents, and child terms. Done means both grouping terms are added with the specified relationships and identifiers, with ontology validation confirming the hierarchy.
