Small arteries and larger arterioles preceding the separate muscle and submucosal–mucosal vasculatures control about 70% of the intestinal vascular resistance insomnia wikipedia purchase sominex 25 mg on-line. The small arterioles of the muscle sleep aid 100 mg sominex 25 mg cheap, submucosa sleep aid l-theanine purchase 25 mg sominex, and mucosal layers can partially adjust blood flow locally to meet the needs of these small areas of tissue. The intestinal vasculature is unusual because branches from a common set of vessels located in the submucosa serve three different tissues, the muscle layers, submucosa, and mucosal layer. Small arteries and arterioles preceding the separate muscle, submucosal, and mucosal vasculatures regulate most of the intestinal vascular resistance. Autoregulation efficiency in the small intestine is modulated by intestinal oxygen consumption. Compared with other major organs, the circulation of the small intestine has a poorly developed autoregulatory response in most conditions. As a result, blood flow usually declines in response to locally decreased arterial pressure because resistance does not adequately decrease to help counteract the effect of low pressure on blood flow. Results of experiments on autoregulation in the small intestine indicate that the intestine is a poor autoregulator of blood flow when it is not occupied with digestion, and thus, its oxygen consumption is low, whereas it is a much better autoregulator during digestion, when its oxygen consumption is high. An understanding of this phenomenon is clear if one realizes that what the intestine needs during high metabolic demand is the oxygen in the blood more so than the blood itself. This can be accomplished by opening more capillaries, thereby increasing extraction of oxygen from the blood flow the intestine is receiving, rather than increasing total blood flow in order to increase total bulk oxygen delivery to the intestine. Applying this concept to the response of intestinal blood flow to a drop in arterial pressure, it follows that if perfusion pressure to the intestine were to drop, causing an initial drop in flow, the intestine could obtain the oxygen it needed to compensate for the drop in blood flow by simply taking the flow it gets and extracting more oxygen from it, rather than initiating an autoregulatory vasodilation to restore total flow. Indeed, this is exactly what happens as the intestinal permeability surface area coefficient increases, following a drop in perfusion pressure and blood flow, before frank vasodilation of the arterioles are used to correct the decrease in flow. Thus, when intestinal metabolism is low, a local decrease in oxygen delivery, brought on by an initial drop in blood pressure and blood flow, is compensated for first by dilating precapillary sphincters to open more capillary surface area for diffusion of oxygen. Should demand increase or total flow be compromised further, more capillaries will open until perfused capillary surface area is maximized. At that point, any further compensation for the effects of a drop in perfusion pressure and blood flow would have to be met by autoregulation of blood flow. In short, when oxygen delivery to the intestine is compromised, the intestine extracts more oxygen from its blood supply first and adjusts its total blood supply second. While in this state, with oxygen extraction essentially maximized, any reduction in oxygen supply to the intestine caused by a temporary local drop in perfusion pressure and blood flow is then compensated for by strong local autoregulation. The fact that the intestine seems to extract oxygen from blood before altering vascular resistance has a certain appeal for whole-body homeostatic mechanisms. Even though effects of changes in vascular resistance in the intestine on the body as a whole are lessened by the parallel arrangement of organ circulations in the body, the intestine and splanchnic circulations are still enormous. Manipulating extraction of oxygen before adjusting vascular resistance and flow might be a means of meeting the metabolic needs of the intestine while minimizing the effects of those needs on the blood supply to other organs. Effects of elevated venous pressure on fluid filtration by intestinal capillaries. The intestine has one of the highest capillary filtration coefficients among organ systems in the body. This could be potentially troublesome because the small intestine has a very large anatomical capillary surface area and it is not a good autoregulator of blood flow for most of the time during the day (i. These two factors make the intestine a prime source of fluid loss in the body whenever mean capillary hydrostatic pressure increases, such as what might occur whenever arterial or venous pressure increase. Recall that, when arterial pressure is increased, strong autoregulation in an organ not only controls organ blood flow, but it also attenuates any increase in mean capillary hydrostatic pressure that would otherwise cause increased capillary fluid filtration. In a weak autoregulatory state, arteriolar constrictor responses to an increase in arterial pressure are weak and loss of fluid through the intestinal capillaries is likely. Furthermore, loss of fluid from the capillaries of the huge intestinal circulation could be significant in situations in which intestinal venous pressures rise. Such venous pressure rises can occur in liver disease or with portal vein obstructions because the intestinal veins are connected in series to the portal circulation of the liver. However, elevation of venous pressure in the intestinal circulation, which would increase capillary hydrostatic pressure, causes sustained myogenic arteriolar constriction that decreases capillary hydrostatic pressure. This is called the venous–arteriolar response and is a means by which major fluid loss from the capillaries is prevented in the intestine in the face of an elevation of intestinal venous pressure. Although the venous arteriolar response occurs in other organ systems, it appears to be strongest in the intestinal circulation.
