carried out by enzymes. Mechanical digestion: Is the physical breaking down of larger food into pieces to increase its surface area (the higher the surface area‚ the higher the rate of chemical digestion. Peristalsis: the squeezing of the digestive tract that pushes food down in one direction. Bolus: the partially digested food that is swallowed after mastication. Chyme: the partially digested food mixed with the enzymes and acid in the stomach. Bile: The secretion produced by the

Human Digestive System The digestive tract is a series of hollow organs through which food passes: mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine. Each portion is specialized for one or more aspect of the three major functions of the digestive system the secretion‚ digestion‚ and absorption. Accessory organs such as salivary glands‚ liver‚ gallbladder and pancreas have duct that lead into the digestive tract and thus support digestive function. Digestion is defined as the mechanical

“The Difference between the Human Digestive System & the Digestive System of a Cow” Digestion is the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed‚ for instance‚ into a blood stream. Digestion is a form of catabolism; a break-down of macro food molecules to smaller ones. Digestion begins in the mouth‚ for a cow the teeth structure is very different from humans. Instead of having two rows of sharp incisors‚ cows have a single‚ bottom row

The goat is considered a ruminant animal. The digestive system includes the mouth‚ esophagus‚ four stomach parts‚ a cecum‚ a small intestine and a large intestine. Goats have no upper teeth so they use the dental pad‚ lower teeth‚ tongue and lips to eat their food. The four compartments to the stomach are the rumen‚ the reticulum‚ the omasum‚ and the abomasums. The esophagus is what moves food from the mouth to the stomach. It opens into the stomach at the opening of the rumen and reticulum‚ which

Digestive System Study Guide 1. Define the term digestion and explain its significance. The chemical and mechanical process of breaking down food and its absorption. Its essential to maintaining life. 2. Distinguish between mechanical digestion and chemical digestion. Chemical digestion is where complex food molecules are broken down to the basic building blocks by enzymes. Mechanical digestion is chewing‚ churning and segmentation. 3. Discuss the five digestive processes that overview the many functions

The Digestive System The digestive system is made up of the digestive tract—a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus—and other organs that help the body break down and absorb food. Organs that make up the digestive tract are the mouth‚ esophagus‚ stomach‚ small intestine‚ large intestine—also called the colon—rectum‚ and anus. Inside these hollow organs is a lining called the mucosa. In the mouth‚ stomach‚ and small intestine‚ the mucosa contains tiny
