The teeth are responsible for grinding food‚ while the tongue assists the mixing of the food with saliva‚ which is secreted by the salivary glands‚ thereby initiating the chemical

In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

The digestive system is a group of organs that perform the process by which food‚ containing nutrients‚ is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.<br><br>The first step of digestion begins at the mouth‚ where the food enters the mouth. Saliva is secreted from the salivary glands

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE

Ad1 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. The digestive process also involves creating waste to be eliminated. The digestive track (gut) is a long twisting tube that starts in the mouth and ends at anus. It’s made up of a series of muscles that coordinate the movement of food and other cells that
