digestion takes place in the mouth. The process? We rip away the food with our canines‚ bite it into small chunks with our incisors and grind the food with our molars/pre-molars. This process stimulates the exocrine glands in the mouth to release digestive enzymes such as salivary amylase‚ which aids in the break down of the food‚ particularly carbohydrates. Chewing the food also causes the release of saliva‚ which helps condense food into a bolus that can be easily passed through the esophagus

Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles‚ providing energy for the regulation of blood glucose‚ preventing

Body Part Function Mouth Entrance point for food; initiates the digestion process. Tongue Contains taste buds; aids in chewing and swallowing Salivary Glands Parotid: limit the extent of swelling when they are inflamed. Sublingual: produce mucin which is found in saliva. Submandibular: produces 70% of saliva made in the body. Pharynx Carries air to the trachea; carries food to the esophagus. Esophagus Carries bolus from mouth to the stomach. Cardiac Sphincter Prevents backflow of food

digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food has reached the stomach‚ the food goes through the process

Upon ingesting food into the mouth‚ salivary glands secrete saliva which contains the digestive enzyme ‘Salivary Amylase’. This has a neutral pH and

Mouth- moistening of food due to the action of the salivary glands‚ polysaccharides breaks down by the salivary amylase. 2. Pulpy acidic fluid called chyme enters the stomach. Stomach acids destroy bacteria in the chyme. 3. In the small intestine (duodenum) and pancreas polysaccharides firstly breaks down into the disaccharides due

Living Digestion The first step in the journey of a sandwich is the mouth‚ where mastication occurs. The salivary glands secrete saliva which includes enzyme amylase. The teeth masticate and reduce the food into smaller pieces. The tongue moves the food around and enables swallowing. While the food is being broken into smaller pieces‚ amylase breaks down the carbohydrates found in the bread. After chewing (or mastication) is done‚ the food moves down the esophagus through peristalsis. The epiglottis
