hi
mm i was trying to work on my exam review, but i really can’t find some of the answers..
well most of it..
can anybody help me?

these are the questions.. might be alot.. O_o;

3.What is the type of epithelial tissue that is designed for absorption and secretion found throughout much of the GI tract?

4.Trace the course of a food bolus as it enters the epithelial tissue esophagus and leaves the rectum?

5.An incision into the wall of the GI tract would cut the mucosa, submucosa, muscularis, and serosa.

1) A person’s blood has high cholecystokinin levels. What does this tell you about the presence or absence of chyme in the small intestine?

2) Some pathogenic bacteria in food can survive the stomach and small intestine, reaching the large intestine. There, they attack the lining of the colon. This irritates the colon, and goblet cells in the colon are stimulated to produce more mucus. This extra mucus can inhibit water absorption through the colon. What common digestive abnormality does this cause?
