Anxiety does evoke the same fight or flight response that stress does, which means, like stress, anxiety will trigger a flood of stress hormones like cortisol designed to enhance your speed, reflexes, heart rate, and circulation.
The organs produce digestive chemicals (enzymes and acids) that break down the nutrients into simpler forms so that absorption through the intestinal wall and into the blood stream can occur.

Mechanical and Chemical Digestion. There are two kinds of digestion: mechanical and chemical.
Chemical digestion that occurs in the stomach is mainly via enzymes and hydrochloric acid. The stomach secretes pepsinogen which turns into pepsin and breaks down proteins.The hydrochloric acid provides a low pH level in which the enzymes can thrive.hemical digestion is the breaking down of food particles through chemical reactions. Chemical and mechanical digestion combine to process food, absorbing nutrients and minerals and discarding the waste. Very little mechanical digestion occurs outside of the mouth.
