The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database.

Term:heart morphological measurement

Accession:CMO:0000016 term browser browse the term
Definition:A measurement of the physical form or structure of the heart, the chambered, muscular organ in vertebrates that pumps blood received from the veins into the arteries, thereby maintaining the flow of blood through the entire circulatory system.
Comment:This is the term which was just "heart measurement". Since it was under body morphological measurement it seemed to clearly refer to a morphological measurement. I made this term more specific so that another term for "heart measurement" could be added to the ontology above it which would also be a parent to other non-morphological heart-related terms.
