What primarily makes up intestinal gas?

Explanation:
Intestinal gas mainly comes from swallowed air and the gases produced by bacteria in the colon. When you swallow air, it adds nitrogen and oxygen that can accumulate in the gut. In the colon, resident bacteria ferment undigested carbohydrates and other substrates, releasing gases such as hydrogen, carbon dioxide, and often methane and sulfur compounds that contribute to odor. Chyme is the semi-fluid mass of partly digested food, not gas. Bile pigments are breakdown products of hemoglobin and do not constitute intestinal gas. Digestive enzymes are substances that help digestion, not the primary components of gas.
