The Structure and Function of the Digestive System Mouth. The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.mall intestine. Made up of three segments — the duodenum, jejunum, and ileum — the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver.

Small Intestine Partially digested food, or chyme, from the stomach is mixed with bile from the liver and pancreatic juice from the pancreas to complete its digestion in the duodenum. The jejunum is the middle section of the small intestine that serves as the primary site of nutrient absorption. It measures around 3 feet in length.

The Digestive System The digestive system is a tube through which food passes from the mouth where food is ingested to the anus where it is egested. It consists of a series of organs, each with a distinct structure and function. During the digestive transit food is broken down into substances suitable for absorption into the bloodstream.

Digestive System Food begins its journey through the digestive system in the mouth, also known as the oral cavity. Inside the mouth are many accessory organs that aid in the digestion of food—the tongue, teeth, and salivary glands.

Human digestive system Mouth and oral structures. Little digestion of food actually takes place in the mouth. However, through the process of mastication, or chewing, food is prepared in the mouth for transport through the upper digestive tract into the stomach and small intestine, where the principal digestive processes take place.

The Digestive Tract and Body Cavities The digestive tract is a tube, which begins at the mouth and ends either at a cloaca or a nus. It processes food, which moves by peristalsis through the process of digestion, absorption and elimination.

Digestive System A Journey Through the Digestive System. As you chew your food and swallow, the food travels through your esophagus -- which is the passageway that connects your mouth to your stomach. In the stomach, strong acids and enzymes digest, or break down, the food into small particles.

Digestive System The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines.he digestive system uses 3 main processes to move and mix food: 1  Swallowing. 2  Swallowing is the process of using smooth and skeletal muscles in the mouth, tongue, and pharynx to push food out of the mouth, through the pharynx, and into the esophagus.

Small Intestine Partially digested food, or chyme, from the stomach is mixed with bile from the liver and pancreatic juice from the pancreas to complete its digestion in the duodenum. The jejunum is the middle section of the small intestine that serves as the primary site of nutrient absorption. It measures around 3 feet in length. The ileum is the final section of the small intestine that empties into the large intestine via the ileocecal sphincter. The ileum is about 6 feet long and completes the absorption of nutrients that were missed in the jejunum.

Absorption Digested food is able to pass into the blood vessels in the wall of the small intestine through the process of diffusion. The inner wall, or mucosa, of the small intestine is covered in wrinkles or folds called plicae circulares that project microscopic finger-like pieces of tissue called villi, which in turn have finger-like projections known as microvilli.

Digestion canals, through which food passes. Human digestion begins in the mouth. There the food is chewed and mixed with saliva, which adds moisture and contains the enzyme amylase that begins to break down starches. The tongue kneads the food into a smooth ball (bolus), which is then swallowed. The bolus passes through the pharynx and esophagus into the stomach, propelled by peristaltic muscular contractions. In the stomach the food is mixed by peristaltic

Digestion and Absorption of Food - The Human Physiology The GI tract begins at the mouth, where digestion begins with chewing. Saliva containing mucus and the enzyme amylase is secreted from 3 pairs of salivary glands, located in the head. Mucus moistens the food and amylase partially digests polysaccharides (starches).

Structure of the Digestive Tract Wall Structure of the Digestive Tract Wall The digestive tract, from the esophagus to the anus, is characterized by a wall with four layers, or tunics. The layers are discussed below, from the inside lining of the tract to the outside lining: The mucosa is a mucous membrane that lines the inside of the digestive tract from mouth to anus. Depending on the section of the digestive tract, it protects the digestive tract wall, secretes substances, and absorbs the end products of digestion. It is composed of three layers: The epithelium is the innermost layer of the mucosa.

The Stomach As food passes through the esophagus, it reaches the cardia, the junction at which the esophagus attaches to the stomach. The cardia secretes mainly mucus and HCO3-. Passing through the lower esophageal sphincter, the food will then enter the stomach which is comprised of 3 parts: the fundus, corpus (body), and antrum. The fundus is the most superior portion of the stomach; superior to the fundus is the diaphragm and lateral to it is the spleen. The right (medial) side of the corpus is relatively straight and is known as the lesser curvature while the left (lateral) side of the corpus is known as the greater curvature.

- From the stomach, the partially digested food passes through the  pyloric sphincter and enters the duodenum, the first part of the  small intestine. In the small intestine, …the tiny bumps called  villi absorb the nutrients as the food go by.

Ducts from the gall bladder and pancreas feed fluids rich in bile salts and digestive enzymes into the duodenum.

How Does Food Travel Through the Digestive System? How does food travel through the digestive system? Quick Answer. Food begins its journey through the digestive system in the mouth, before being pushed by a series of involuntary muscle contractions through the esophagus, then the stomach, and then the small and large intestines.
