    Anatomy and Physiology Digestive System

    The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Most absorption takes place in the walls of the small intestine, which are densely folded to maximize the surface area in contact with digested food. The body also uses saliva to lubricate food as it passes through the mouth, pharynx, and esophagus.

    It takes many waves of peristalsis for food to travel from the esophagus, through the stomach and. In this lesson, you will learn about bile and its role in the breakdown of dietary fats. Teeth are living organs and contain blood vessels and nerves under the dentin in a soft region known as the pulp.

    These folds are used to maximize the digestion of food and absorption of nutrients. This storage capacity allows the body to eat only a few times each day and to ingest more food than it can process at one time. Carbohydrates are an important energy source, but must be broken down to be absorbed out of the digestive tract. At the inferior end of the esophagus is a muscular ring called the lower esophageal sphincter or cardiac sphincter.
