Perisztaltikája

Perisztaltikája refers to the involuntary wave-like muscular contractions that move food through the digestive tract. This process is crucial for the efficient digestion and absorption of nutrients. It begins in the esophagus, where peristalsis propels food from the mouth down to the stomach. Once in the stomach, the muscular walls churn and mix the food with digestive juices. From the stomach, peristaltic waves continue through the small intestine, further breaking down food and absorbing nutrients into the bloodstream. Finally, the process moves through the large intestine, where water is absorbed and waste material is formed and eventually eliminated from the body. The coordinated action of smooth muscles in the walls of these organs is responsible for this continuous, rhythmic movement. Factors such as the presence of food, hormones, and nerve signals regulate the speed and intensity of peristaltic contractions. Disruptions to peristalsis can lead to various digestive issues, including constipation, diarrhea, and nausea.
