Digestive system and Health problems

• Food passes through the esophagus (food pipe) into the stomach.
• The stomach is where food is mixed with digestive juices to break it down into smaller pieces.
• Digestion begins when we chew our food, breaking it up into small pieces that can be swallowed easily.
• The stomach is where food is mixed with digestive juices to form chyme, which then moves on to the small intestine.
• In the small intestine, nutrients are absorbed by the body while waste products move towards the large intestine.
• Water is reabsorbed from the contents of the large intestine, forming feces that pass out of the anus as solid or liquid waste.
• Undigested material continues on to the large intestine, also known as the colon.
• When we swallow, the food travels from the mouth along the throat and into the esophagus.
• In the small intestine, nutrients are absorbed by the body.
• This LES relaxes to allow food to pass into the stomach, but then closes again so acidic gastric juice doesn’t come back up into the esophagus.
• Digested food then moves into the small intestine, which has three parts - duodenum, jejunum, and ileum.
• Nutrients are absorbed by the walls of the small intestine and carried away by blood vessels to different parts of the body.
• In the small intestine, enzymes from the pancreas and bile from the liver further break down the food particles.
• Nutrients are absorbed by the walls of the small intestine and carried away by blood vessels to different parts of the body.
• At the end of the esophagus, there's a ring-like muscle called the lower esophageal sphincter (LES).
• Waste products left over from digestion move into the large intestine.
• Stool is eliminated from the body through defecation.
• Water is reabsorbed from the contents of the large intestine, forming feces or stool.
• Enzymes are chemicals produced by living organisms that speed up chemical reactions without being used up themselves.
• The stomach produces hydrochloric acid that helps kill bacteria and other microorganisms in our food.
• The stomach produces hydrochloric acid that helps kill bacteria and activates digestive enzymes.
• The large intestine is where water is reabsorbed from undigested material, forming feces that are stored until they leave the body through defecation.
• The stomach is located between the esophagus and the small intestine.
• Enzymes from the pancreas and bile from the liver further break down the food particles in the small intestine.
• Enzymes are proteins produced by cells that speed up chemical reactions without being used up themselves.
