DIGESTIVE SYSTEM FUNCTION -The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are several important accessory organs that help your body

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 produce enzymes and hormones‚ to aid in

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth

or help absorption of vital nutrients and help disposal of waste. The structure of the digestive system starts with the gastrointestinal tract‚ it is a tube that runs from the mouth to the anus and because of this some scientist says it is an external organ; there are also accessory organs for digestion‚ the salivary glands‚ teeth‚ tongue‚ liver‚ gall bladder and pancreas. The function of the digestive system is to breakdown food‚ so nutrients can enter the blood and lymph system. To start

Digestive disorders 1. Diarrhea is a symptom that can last for one or two days mainly. Diarrhea is when feces move too quickly through the bowels and the intestines do not have time to pull water from the waste to make it firm.

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
