WebThe splanchnic circulation comprises the gastric, small intestinal, colonic, pancreatic, hepatic, and splenic circulations. They are arranged in parallel and fed by the celiac artery and the superior and inferior mesenteric arteries. The resistance arterioles are the primary determinant of vascular resistance in the splanchnic circulation. WebOH, also called postural hypotension or orthostasis, is defined as a drop in systolic pressure of 20 points or more or in diastolic pressure of 10 points or more, within 3 minutes of standing as compared to the reading while supine (Hogan-Quigley et al.; Lanier et al., 2011 ).
