Blood flow and absorption from the rumen
Abstract:
Blood flow to the ruminoreticular epithelium varies cyclically with feeding. Within this range the absorption of rapidly penetrating solutes will be dependent on the blood flow. For HTO absorption, the most satisfactory model suggests the involvement of a countercurrent exchanger behind the epithelium. The consequences of this arrangement are presented, and are qualitatively consistent with known effects of solute absorption on net water movement. The control mechanisms for net water absorption are not fully identified. The observed blood flows in the splanchnic region raise interesting questions of functional changes in the omasum and fat.

Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...
Drug Absorption: Overview
When drugs are injected intravenously, they directly enter the systemic circulation. Alternatively, orally administered drugs navigate through the gastrointestinal (GI) tract.
Factors Influencing Drug Absorption: Anatomical Parameters
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
