What is the name of the wave like constraction that propel food along the gut?
Peristalsis is the process by which smooth muscle moves a mass of food (called the food bolus) through the digestive system. There is circular smooth muscle and longitudinal smooth muscle in the digestive tract. Contraction of circluar smooth muscle keeps the food bolus from moving "backward" along the digestive tract by decreasing the diameter of the tract behind the bolus. Contraction of the longitudinal muscle in the digestive tract propels the food bolus "forward" in the digestive tract.

Where does a bolus of carbohydrates travel in the digestive system from mouth to anus?
Bolus goes down esophagus, through lower esophageal sphincter (aka, cardiac sphincter) and into stomach. (A sphincter is a circular muscle which squeezes shut or opens the tubular digestive tract). It then passes through pyloric sphincter into small intestine. The small intestine is made up first of the duodenum, then jejunum, then ileum. From ileum, bolus goes to ascending colon, then transverse colon, then descending colon. From there to rectum and then out through anus (anal sphincter) .
What is the muscle action that mixes chyme with digestive juices while another muscular action that moves food through the digestive system?

The muscles help to move the bolus (food) through the digestive tract. Peristalsis are located all over the digestive tract.
