The digestive system is a combination of organs which have been arranged together to help carry out its particular function of turning food into the energy which is necessary to survive and packaging the excess residue for waste disposal. Digestion involves the breakdown of food into smaller components. The process of digestion has many stages with the first starting in the oral cavity. Within the system‚ food passes through a tube called the alimentary canal‚ more commonly known as the gastrointestinal

The Circulatory System The Circulatory System is designed to deliver oxygen and nutrients to all parts of the body and pick up waste materials and toxins for elimination. This system is made up of the heart‚ the veins‚ the arteries‚ and the capillaries. Circulation is achieved by a continuous one-way movement of blood throughout the body. The network of blood vessels that flow through the body is so extensive that blood flows within close proximity to almost every cell. Heart The heart

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

“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

6 primary functions of digestive system: 1. Ingestion- food intake 2. Secretion 3. Digestion- mechanical & chemical breakdown of food Mechanical Mastication- first step. Enables mixing with saliva to form bolus to be swallowed. Regulated by CNS. Deglutition Mixing/Churning Peristalsis- movement of muscles within GI tract that facilitates movement of food Chemical- Hydrolysis (using H2O) of macromolecules into monomers (residues) carried out by digestive enzymes produced by salivary glands
