Digestion begins in the mouth when one eats food. It begins the moment one takes a sandwich bite. The teeth are used to break the sandwich that contains lettuce and pickles into smaller particles or boluses so that the enzymes can digest the food much easier. Lettuce contains carbohydrates‚ proteins and fat. The tongue helps turn food in the mouth and mix with the saliva in the mouth which contains salivary amylase enzyme. It then passes through the esophagus to the stomach which is a mixer and grinder

to physically see and touch the anatomy of the mammalian body rather seeing it solely in text form. This gives us a better idea of how the structures are intertwined to form the body as a whole. On the first day of the lab I observed the pig’s digestive system which includes the liver‚small intestines‚ large intestine‚ and the pancreas. The liver was the largest organ in the fetal pig’s body and was shaped like small bean bag. I was actually surprised when seeing the small intestine because I didn’t

that been absorbed by the human body is called digestion.Digestion is split into two different processes which are physical digestion (grounding of large molecules of food into smaller particles) and chemical digestion (enzymes released into the digestive tract use to break down large polymeric biomolecules into monomers or oligomers (dimers or trimers). Both ingestion and digestion occurs in the mouth or oral cavity(Campbell et al.‚ 2008). Physical digestion begins in the oral cavity. There are

The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands. Saliva moistens the food and carries dissolved food molecules to the taste buds. Saliva helps digest food because it contains enzymes that start to break it down. After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that

It was not primarily used as an organ of digestion‚ but it secreted a digestive enzyme called bile. The bile was used to break down fats. Then‚ the esophagus‚ small intestines‚ spleen‚ large intestines‚ male reproductive organs‚ and fat bodies were located and observed. The esophagus was a tube that led from the frog’s mouth
