Digestive Tract Comes into contact with materials passing through mouth esophagus stomach small intestine large intestine anus pharynx Accessory Does not come into contact with material passing through, but aids in digestion liver gallbladder pancreas Organ Functions: Match each digestive system organ to its correct description. Gallbladder Releases bile when eating greasy foods that are high in fat to help aid in digestion Liver Gets rid of toxins in the body and also creates bile Mouth Saliva mixes with food here and it is broken up into smaller pieces Small Intestine Food starts out semi-solid and leaves here as a liquid; where most nutrient absorption occurs Large Intestine Food starts out as a liquid and leaves as a solid; water is removed from the waste. Esophagus Muscles contract (peristalsis) to move the food to the stomach Pancreas Creates enzymes that help break down fats, proteins, and carbs; also creates insulin Rectum Lets the brain know that it is "time to go #2" Anus This is constantly flexed, but when you "go" it relaxes Stomach Enzymes and acid mix with food here to break down the food into chyme Which is the longest part of the small intestine? ileum duodenum jejunum ascending small intestine Digestion begins in the mouth. Which of the following statements is INCORRECT? The salivary glands release mucus that helps chemically digest food. Saliva contains digestive enzymes that help chemically break down food.

Large Intestine Esophagus Small Intestine Pancreas Our throat divides into two separate tubes - the trachea (windpipe) and the esophagus. What prevents food from entering the trachea? Epiglottis Tongue Glottis Larynx What happens when food reaches the stomach? Nothing. No digestion occurs in the stomach. The food moves quickly into the small intestine so no nutrients are lost. Juices mix with the food and stomach muscles churn it. The food is completely digested and absorbed by tiny blood vessels in the walls of the stomach. The _ salivary glands are located on the face in front of each ear. Maxillary Sublingual Parotid Submandibular The _ are the posterior teeth used for grinding and chewing.
