Table 1 Examples of CQs
From: A histological ontology of the human cardiovascular system
| Classification |
| What are the organs of the cardiovascular system? |
| What is the composition of the myocardium? |
| What are the muscular arteries? |
| Properties |
| What are the tunics in veins? |
| Which is the constitution of a media tunic? |
| What are the structures present in the large veins? |
| Constraints |
| A simple epithelial tissue cannot be stratified |
| A capillary is only composed of endothelium |
| An organ can have three tunics maximum |
| Inferences |
| If a set of cells is close to a light region, then the tissue is probably an |
| epithelial tissue |
| If an organ has a thin media tunic as well as a thick adventitia tunic and |
| a wide light region, it is probably a vein |
| If an organ has a thick media tunic and a small light region, it is probably |
| an artery |
