HUMAN NUTRITION

Detailed explanation-1: -Food is mixed with gastric juice. Strong muscular contractions in the stomach wall reduce the food to chyme – a thick milky material. The pyloric sphincter at the lower end of the stomach slowly releases chyme into the duodenum.

Detailed explanation-2: -Food enters the duodenum through the pyloric sphincter in amounts that the small intestine can digest. When full, the duodenum signals the stomach to stop emptying.

Detailed explanation-3: -Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.

Detailed explanation-4: -Although it is a single organ, several different parts of the stomach exist: the fundus, body, antrum and pylorus. Food passes through the pylorus and into the duodenum where further digestion occurs.

Detailed explanation-5: -The GI tract is the pathway food takes from your mouth, through the esophagus, stomach, small and large intestine. In the GI tract, nutrients and water from foods are absorbed to help keep your body healthy. Whatever isn’t absorbed keeps moving through your GI tract until you get rid of it by using the bathroom.
