The bolus then moves down into the esophagus, which follows to the stomach. Once the bolus engages the stomach, it starts to mix with the acid secretions convert the bolus into chyme. Chyme is the semi-fluid mass of in some measure of digested food discharged from the stomach in to the duodenum. Relying on the size and type of meal consumed, chyme usually empties from the stomach in 2 to 6 hrs. The liver, gallbladder and the pancreas begin to bestow to the digestive process once the chyme reaches the small intestine.
The pancreas secretes trypsin and chymotripsin. The liver and gall bladder secrete bile, used for the emulsification of fats. The second section of the small intestine, the jejunum, is where the majority of food is absorbed into the bloodstream. The last section of the small intestine, the ileum, is where the remainder of nutrients is absorbed. What is not absorbed by the small intestine passes into the large intestine, which includes the colon and rectum.
Bolus is simply food in its chewed state. The bolus is then swallowed and enters the stomach. In the stomach, food or bolus is further digested with the stomach acids and is broken down even further to prepare to enter the intestinal tract. The stomach contracts and relaxes to push digested food into the small intestine. Once inside the small intestine, enzymes are released that allow the usable parts of the food to be absorbed into the body for energy.
The small intestine is the principal site of digestion and absorption. Enzymes from the pancreas, liver, gallbladder, and the small intestine itself combine to break down nutrients so that they can be absorbed. The pancreas supplies enzymes to digest proteins, fats and carbohydrates. The live produces bile required for emulsification of fat, and the gallbladder stores the bile until it is needed. The absorption of nutrients in the small intestine is facilitated by tiny projections called villi, which provide more surface area for absorption.
Peristalsis also is at work in this organ, moving food through and mixing it with digestive secretions from the pancreas and liver. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream. Pancreas-The pancreas secretes digestive enzymes into the duodenum, the first segment of the small intestine. These enzymes break down protein, fats, and carbohydrates. The pancreas also makes insulin, secreting it directly into the bloodstream.
When the food is ready to be swallowed, the food is now called a soft mass called a ‘bolus’. This bolus is then propelled down through the pharynx and into the oesophagus. Peristalsis (alternating
It coats the chewed food and transforms it into what is called a bolus. An enzyme called amylase found in the saliva breaks down the carbohydrates in the bolus into simpler sugars. By breaking down the food, the bolus becomes mushy, slippery and easy to swallow. The tongue also plays a big role in helping digest food in the mouth. It helps taste, transport and swallow food.
The mouth receives food and begins digestion by mechanically reducing the size of the solid particles and mixing them with saliva. Pharynx – The pharynx is in both the respiratory system and digestive system. The pharynx is a muscular tube, at the back of your throat when the nose and mouth join. This serves as a passageway for food and air. The tube being so muscular helps an individual with swallowing.
The stomach is not only our digestive system it absorbs food but, rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of our intestines( Stomach and role in digestion). The Mucous cell, parietal cell, chief cell, and G cell all make up the four main cell types that spread all over the inner structure of the stomach (Stomach and role in digestion). The mucous cell produce mucus from preventing the epithelium from hydrochloric acid. Which is found in the fundic, cardiac, and pyloric region (Stomach and its role in digestion). (Ireland, 2012) Stated “Hydrochloric acid is one of the strongest acids used in laboratories and can be found in our stomach, as PH2.
The pancreas is an organ located behind the stomach that produces chemicals called enzymes, as well as the hormones insulin and glucagon. These enzymes are usually only active after they reach the small intestine, where they are needed to digest food. When they somehow become active inside the pancreas, they digest pancreatic tissue causing swelling, bleeding and damage to blood vessels. Acute pancreatitis affects men more often than women. Certain diseases, surgeries, and habits make one more likely to develop this condition.
