Digestion

Asked by AkshayPathak12 | 15th Apr, 2010, 07:15: PM

Expert Answer:

Mucus does not digest in the intestinal tract, so mucus commonly appears in fecal matter whether its origin is from the intestines, or swallowed.

 

In the duodenum, gastric acid is neutralized by sodium bicarbonate.The neutralization is described by the equation:

HCl + NaHCO3 → NaCl + H2CO3

The carbonic acid instantly decomposes into carbon dioxide and water, then gets eliminated through urine.
