Answer:
the mouth; starch in maize; is digested by salivary amylase/ptyalin/diastase into maltose; food is chewed and mixed by teeth and the tongue; rolled into boluses by peristalsis; it enters into the stomach via the cardiac sphincter; in the stomach, gastric juice containing pepsinogen that is activated to pepsin; digests proteins in the beans; into shorter peptides; food is churned and allowed into the duodenum; via the pyloric sphincter muscle; in the duodenum; bile juice secreted by the gall bladder; emulsifies the oils in the beans into tiny oil droplets; pancreatic juice; secreted by the pancrease; contains pancreatic amylase; that digests starch to maltose; pancreatic lipase; that digests the oil in the beans to fatty acids and glycerol; trypsin; digests proteins into shorter peptides; food enters into the ileum; where succus entericus is secreted; it contains maltase enzyme; that digests the maltose into glucose; that is absorbed; peptidase; digests peptides into amino acids; lipase digests the remaining lipids (oil) into fatty acids and glycerol; which is absorbed through the lacteals of the villi;

Corn and beans are digested normally, but their cellulose layer, our digestive system is not able to digest them.
Why do beans and corn come out whole in the poop?
With smaller teeth, we chew food partially, as in the case of corn and beans in which the outermost coating releases the innermost grain.
The outer covering of corn, for example (the yellow part), is almost entirely cellulose, which today is incapable of being digested with the digestive system that we have acquired through evolution.
It passes through the entire intestine untouched, and comes out looking like a whole grain, even though it's just the outside. The inside of the grain is starchy and digestible, and that's the part we can actually eat.
With this information, we can conclude that Corn and beans are digested normally, but their cellulose layer, our digestive system is not able to digest them.
