Digestive System- My directions were to start with the stomach and describe what happens to the food as it goes through the digestive system
The food in the stomach gets physically ground up and chemically worked on by the gastric juices. At the end of this process, this mixture of partially digested food and gastric juices is given the name chyme... From the stomach, the chyme travels through the pyloric sphincter valve (which opens when the stomach is full, it allows only small amounts into the small intestine at a time) and into the duodenum, the first part of
and sigmoid colon. The large intestine is about 6 centimeters in diameter and 1.5 meters long. The large intestine absorbs water from the material remaining in the digestive tract. When most of the water has been removed from the undigested material, a solid waste matter, called feces remains. Peristalsis propels feces through the large intestine and into the rectum, the last few inches of the large intestine. Feces collected in the rectum is eliminated through the anus.
