Splanchnic circulation

Control of the Splanchnic Circulation 1

The major regulatory factors in the mesenteric circulation include general hemodynamic forces, the autonomic nervous system, circulating vasoactive substances, tissue metabolites and intrinsic characteristics of vascular smooth muscle. During mesenteric ischemic states smooth muscle spasm elevates resistance to blood flow and aggravates intestinal tissue hypoxia leading to mucosal necrosis. Clo...

Control of the Splanchnic Circulation in Man

Some effects of the /3-adrenergic receptor blocker, propranolol, were studied in 20 normal, fasting, conscious men. The measurements made included cardiac output, splanchnic blood flow and oxygen consumption, arterial and hepatic venous blood pressure, and heart rate. The intravenous administration of propranolol (0.13 mg/kg) was followed by significant reductions in splanchnic blood flow and o...

Responses of the splanchnic circulation to ischaemia.

The distribution of the cardiac output is conventionally shared between six major circulatory components, that is, to the brain, heart, kidneys, bone and skeletal muscle, skin and viscera. This last comprises the splanchnic circulation, which arrives through the three great visceral arteries (coeliac axis, superior and inferior mesenteric artery) and is drained, via the liver, into the hepatic ...
