GIST Support International - Glossary of Terms
| Definition |
| vascular | Relating to the blood vessels of the body. The blood vessels of the body, as a group, are referred to as the vascular system. The blood vessels are made up of arteries, veins and capillaries -- arteries that pass oxygen-rich blood to the tissues of the body; veins which return oxygen-depleted blood from the tissues to the lungs for oxygen; and the capillaries that are the tiniest vessels and are between the arteries and veins. GISTs are often called "highly vascular tumors" meaning that they have a rich blood supply. |
