title: Blood flow in the various compartments of the goat stomach.
abstract: Blood flow rates in the mucosa and muscularis sections of the rumen, reticulum, omasum and abomasum of conscious goats have been measured by using radioactive microspheres. Blood flow rates to the rumen mucosa in ml/100 g tissue/min were 33.56 +/- 4.5, 11.64 +/- 3.2 and 7.18 +/- 1.6 under control conditions and during adrenaline and noradrenaline infusions respectively. The flow to the rumen muscularis under similar conditions were 12.5 +/- 2.4, 4.08 +/- 1.3 and 3.14 +/- 0.5. In the fundic mucosa, the blood flow rates were 50.52 +/- 5.8, 14.74 +/- 3.7 and 12.66 +/- 2.6 while the flow rates to the fundic muscularis were 18.26 +/- 3.8, 6.62 +/- 1.8 and 5.58 +/- 1.6. The flow rates to the pyloric mucosa were 31.28 +/- 2.8, 4.29 +/- 2.2 and 3.84 +/- 0.5 while the flow rates to the pyloric muscularis were 14.61 +/- 2.4, 5.42 +/- 1.6 and 4.62 +/- 1.9 ml/100 g tissue/min. the blood flow rates to these varius sections under control conditions were significantly higher than during adrenaline and noradrenaline infusions (P < 0.001) respectively.
