Week 2 Checkpoint: Human Digestion Food Path Salivary glands (which produce saliva) begin the digestive process; it goes through the pharynx (passageway for food and air responsible for swallowing) into the esophagus (portion of gastrointestinal tract going from the pharynx to stomach). This phase last just a couple of minutes and only goes a distance of 5 inches to 1 foot. From there it goes into the stomach afterwards in will go through the liver (organ that secretes bile necessary for digestion and absorption), gallbladder (organ that stores bile produced by liver), and pancreas (secretes enzymes and bicarbonate into the small intestine during digestion) before entering the small intestine. The stomach phase only goes a distance of 1 foot and can last anywhere from 2-6 hours. After leaving the small intestine it goes into the large intestine and ends at the anus (opening of the digestive tract which feces leaves the body).
