The process begins with chewing skittles in the mouth, where salivary amylase breaks down sugar. The bolus then travels down the esophagus via peristalsis into the stomach, further broken down by gastric juice. The pancreas releases enzymes like amylase and lipase to digest sugars and fats.

The small intestine's motility and secretion processes involve various types of contractions and movements, such as segmentation contractions, peristalsis, and the migrating motor complex. These processes play a crucial role in mixing chyme, aiding in digestion, and facilitating absorption of nutrie

Intestinal obstruction can be classified into dynamic and adynamic types, with various causes such as intraluminal faecal impaction, malignancy, and hernia. The pathophysiology involves changes in bowel peristalsis and dilation, leading to potential strangulation and ischemia. Morbidity and mortalit

The lecture discusses the motor functions of the small intestine, including segmentation and peristaltic contractions. It covers factors affecting intestinal peristalsis and the role of gastro-enteric reflex. The small intestine's structure, functions in digestion and absorption, and common disorder

Gastrointestinal motility involves various processes like peristalsis, segmentation, basic electrical activity, and the migrating motor complex. Peristalsis is the reflex response to gut wall stretching, while segmentation helps mix intestinal contents and digestive juices. Basic Electrical Rhythm (

The human digestive system is a complex pathway that starts from the mouth and ends at the anus, involving various organs like the mouth, pharynx, esophagus, and stomach. Each part plays a crucial role in breaking down food particles, absorbing nutrients, and eliminating waste products. From chewing

The gastrointestinal tract (GIT) comprises four layers - Mucosa, Submucosa, Muscularis externa, and Serosa. Each layer plays a crucial role in the digestion process. The GIT undergoes gut motility, including propulsive movements like peristalsis and mixing movements, to facilitate the movement of fo

The stomach plays a crucial role in digestion, from storage and mixing of food to slow emptying of chyme into the duodenum. Gastric motility involves peristalsis and retropulsion, essential for propelling food towards the pylorus. Dr. Muntadher Abdulkareem Abdullah provides valuable insights into th

Explore the stages of the digestive system beginning with the first stage in the mouth where digestion starts with the help of teeth. Learn about the movement of food through the esophagus, breakdown in the stomach, and absorption in the small intestine. Discover the role of peristalsis in moving fo
