| vasodilation | The increase in the internal diameter of a blood vessel that results from relaxation of smooth muscle within the wall of the vessel. This causes an increase in blood flow, but a decrease in systemic vascular resistance. (27 Sep 1997) |

| vasodilative | 1. Causing dilation of the blood vessels. Synonym: vasodilator. (05 Mar 2000) |
| vasodilator | <physiology> Causing dilation or relaxation of the blood vessels; as, the vasodilator nerves, stimulation of which causes dilation of the blood vessels to which they go. These nerves are also called vaso-inhibitory, and vasohypotonic nerves, since their stimulation causes relaxation and rest. Origin: L. Vas a vessel + dilator. Source: Websters Dictionary (01 Mar 1998) |
| vasodilator agents | Drugs used to cause dilation of the blood vessels. (12 Dec 1998) |
| vasodilator stimulated phosphoprotein | <protein> A 46/50 kD protein that is a substrate for both cAMP and cGMP dependent protein kinases and that is associated with microfilament bundles in many tissue cells. Abundant in platelets, phosphorylation of VASP will inhibit platelet activation. (18 Nov 1997) |
| vasodilators | Agents that act as blood vessel dilators (vasodilators) and open vessels by relaxing their muscular walls. For example, nitroglycerin is a vasodilator. So are the ace (angiotensin-converting enzyme) inhibitors. (12 Dec 1998) |
| vasoepididymostomy | Surgical anastomosis of the vasa deferentia to the epididymis, to bypass an obstruction at the level of the mid to distal epididymis or proximal vas. Origin: vaso-+ epididymis + G. Stoma, mouth (05 Mar 2000) |
| vasofactive | Relating to angiopoiesis. Synonym: vasifactive, vasofactive, vasoformative. (05 Mar 2000) |
| vasoformation | Formation of blood or lymphatic vessels. Synonym: vasifaction, vasoformation. Origin: angio-+ G. Poiesis, making (05 Mar 2000) |
| vasoformative | <physiology> Concerned in the development and formation of blood vessels and blood corpuscles; as, the vasoformative cells. Origin: L. Vas a vessel + formative. Source: Websters Dictionary (01 Mar 1998) |
| vasoformative cell | A cell in the embryo which develops into blood vessel tissue. An embryonic mesenchymal tissue which differentiates into the blood cells and blood vessels. (09 Oct 1997) |
| vasoganglion | A mass of blood vessels. (05 Mar 2000) |
| vasogenic shock | Shock resulting from depressed activity of the higher vasomotor centres in the brain stem and the medulla, producing vasodilation without loss of fluid so that the container is disproportionately large. In oligaemic shock, blood volume is reduced; in both, return of venous blood is inadequate. (05 Mar 2000) |
| vasogram | <investigation> An X-ray study of the vas deferens. (09 Oct 1997) |
| vasography | Radiography of the vas deferens to determine patency, by injecting contrast medium into its lumen either transurethrally or by open vasotomy. Origin: vas + G. Grapho, to write (05 Mar 2000) |
