Answer: After Jessie had a meal of a burger, fries, and water for lunch, the meal went through a series of processes in the digestive system. Here's a general description of what happened to the meal:
Chewing: Jessie started the digestion process by chewing the burger and fries, which breaks down the food into smaller pieces and mixes it with saliva.
Swallowing: Once the food is adequately chewed and mixed with saliva, Jessie swallowed it. The food then traveled down the esophagus, a muscular tube connecting the mouth to the stomach.
Stomach: In the stomach, the burger and fries mix with gastric juices, which contain enzymes and stomach acid. These gastric juices help break down proteins and start the digestion process. The stomach also mixes the food, turning it into a semi-liquid substance called chyme.
Small Intestine: The chyme moves from the stomach to the small intestine, where the majority of digestion and nutrient absorption occurs. Enzymes from the pancreas and bile from the liver help further break down the food into smaller molecules. Nutrients such as carbohydrates, proteins, and fats are absorbed into the bloodstream through the lining of the small intestine.
Large Intestine: Any undigested food particles, fiber, and water move from the small intestine to the large intestine (colon). In the large intestine, water is absorbed, and the remaining material is formed into feces.
Elimination: The feces, containing waste products and indigestible material, are stored in the rectum. Eventually, they are eliminated from the body through the anus during a bowel movement.
