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

as they travel through the organs throughout the digestive system. • Carbohydrates are the body’s preferred energy source‚ and are found in the forms of starch‚ sugar and fibre. Additionally‚ carbohydrates move into the small intestine‚ where enzymes released by the pancreas break those carbohydrates into simple forms‚ so they can be absorbed into the bloodstream. • Lipids that are consumed‚ are mainly fats.

Digestive System We all have to eat food to survive when the average person eat food we don’t think about all the things your body have to do just to digest what we ate this short essay I will explain to you the process of how we digest food. Digestion times vary between people but on the average it takes 24-72 hours for our body’s to digest food. The first process with digestion is ingestion which means the chewing process while we chew food it’s broken up in the mouth with saliva and forms

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

Each step in digestion requires energy‚ and thus imposes an “overhead charge” on the energy made available from absorbed substances The major part of digestion takes place in the

Digestive System: As with any system we are learning in this course‚ the structural anatomy and functions of each are the basis of your learning. Otherwise known as the alimentary canal‚ the best way to learn the digestive system structures and their functions is to follow some food through the process from beginning to end. Where does the food go? As food enters the mouth‚ both mechanical and chemical digestion begins. First the food is physically broken down by the mechanical process

An explanation of the physiology of two named body systems in relation to energy metabolism in the body. (P4) In this assignment I will be explaining the physiology of two named body systems in relation to energy metabolism in the body‚ the Respiration system and the Digestive system. I will start off by giving a definition of energy metabolism in the body. Metabolism in the body is a collection of chemical reactions that takes place in the body’s cells. Metabolism converts the nutrients in the
