organisms. Throughout the digestion process‚ food is broken down into small molecules‚ where it can be absorbed easily. There are many organs that aid in this complex task. Ingestion‚ digestion‚ and absorption are the three necessary steps of the digestive process. First‚ food is ingested. Ingestion takes place in the mouth. Once food enters the mouth‚ teeth chew it. The salivary glands produce saliva‚ which is mixed with food while chewing. Saliva helps break the food into smaller pieces. These

Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

membrane. The alimentary canal walls have four basic layers or tunics. These are the mucosa‚ the submucosa‚ the muscularis externa‚ and either a serosa or adventitia. Each of these layers has a predominant tissue type and a specific function in the digestive process. The mucosa is the wet epithelial membrane abutting the alimentary canal lumen. The major functions of the mucosa are secretion‚ absorption of digested foodstuffs‚ and protection. The submucosa’s major function is nutrition and protection

Human Digestion Activity The digestive process involves the mixing of food‚ the movement of food through the digestive tract‚ and a chemical breakdown of large molecules of food into smaller molecules. The digestive system is made up of the digestive tract and other organs that aid in digestion. The digestive tract is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. Those twisted tubes include the mouth‚ esophagus‚ stomach‚ small and

Probiotics are also available as dietary supplements. Lactobacillus and Bifidobacteria Lactobacillus and Bifidobacteria is a type of bacteria. These are "friendly" bacteria that normally live in our digestive‚ urinary‚ and genital systems without causing disease. Lactobacillus is also found in some fermented foods like yogurt and in dietary

Project 3.2.2: Digestive System Design Introduction During his or her lifetime‚ the average person eats his/her way through at least 20 tons of food. Meats‚ vegetables or sweets - whatever your diet‚ that’s 40‚000 pounds! Our digestive system works to turn this enormous amount of food into substances that the body can use for energy and for growth and repair. But what actually happens to these foods once they enter our bodies? How does the body process each tasty bite and harness the power locked
