broken up pieces of food mix with saliva and break down into a substance called bolus‚ which is a ball of chewed food. Bolus then passes through the pharynx‚ which helps us swallow‚ into the esophagus and into the stomach. The stomach further breaks down the bolus with highly acidic stomach secretion and is turned into a semi liquid mass called chyme. This process could take 2 to 6 hours depending on the amount of food and type of food. The chyme then moves to the small intestine. The small intestine

There are different systems working together and form a human body work permit. One of this system is the important digestive system which consist of a cluster of organs‚ including the mouth‚ stomach and intestines. These organs allow the digestion of food. That means that digestion? It is a process of breaking down food into smaller components to make it easier absorption. There are three main steps in the digestive process: ingestion‚ digestion and absorption. The first step of the digestive process

condition called heartburn; this condition is caused when someone’s stomach produced excess amounts of gastric acids. One of the abundant acids is Hydrochloric Acid (HCl); this acid has a pH level of 1. When there is too much acid in our stomach‚ it rises up to the esophagus‚ which causes the burning sensation known as heartburn. You can treat this if you take antacids‚ antacids are mild bases that can help neutralize the stomach and ends heartburn. GENERAL NEUTRALIZATION EQUATION: Acid + Base =

found in the stomach. It was identified in 1982 by Barry Marshall and Robin Warren‚ who found that it was present in patients with chronic gastritis and gastric ulcers‚ conditions that were not previously believed to have a microbial cause. It is also linked to the development of duodenal ulcers and stomach cancer. However‚ over 80 percent of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology. More

extends from the mouth to the rectum. As food moves through this canal‚ it is ground and mixed with various digestive juices. Most of these juices contain digestive enzymes‚ chemicals that speed up reactions involved in the breakdown of food. The stomach and the small intestines‚ which are parts of the alimentary canal‚ each produce a digestive juice. Other digestive juices empty into the alimentary canal from the salivary glands‚ gall bladder‚ and pancreas. These organs are also part of the digestive
