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.

Mechanical and Chemical Digestion. There are two kinds of digestion: mechanical and chemical.
There are six main groups of enzymes-hydrolases, isomerases, ligases, lyases, oxidoreductases, and transferases. The enzymes involved in food decomposition and in the digestive process are hydrolases. They break down proteins (proteases), carbohydrates (carbohydrases or amylases), and fats (lipases). Plants also contain enzymes to break down fiber (cellulases).
