Zusammenfassung
Die Regulation von Nahrungszufuhr, Nahrungsaufnahme und Verdauung ist komplex. Ein enges Zusammenspiel von verschiedenen Organfunktionen (Essen, Kauen, Schlucken; Magenentleerung, Verdauung, Absorption) muss garantiert sein. Zusätzlich müssen die verschiedenen Verdauungsfunktionen mit Appetit-, Hunger- und Sättigungsgefühlen gekoppelt werden. Die Regulation dieser integrierten Abläufe ist nicht nur hochkomplex, sondern nur unvollständig verstanden. Im vorliegenden Kapitel werden schwerpunktmäßig die gastrointestinalen Signale besprochen; zusätzlich wird deren Bedeutung im Regulationsprozess analysiert.
Abstract
Regulation of food supply, food intake and digestion is a complex procedure. It must be ensured that there is a close interaction of various organ functions (eating, chewing, swallowing; emptying of the stomach, digestion, absorption). In addition, the various digestive functions involving feelings of appetite, hunger and saturation must be linked. Regulation of these integrated procedures is not only highly complex but also incompletely understood. In the following chapter, emphasis is on the gastrointestinal signals; in addition, their importance in the process of regulation is analysed.
