Digestive System Digestion is the mechanical and chemical breakdown of food into smaller components that are more easily absorbed into a blood stream‚ for instance. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. When food enters the mouth‚ digestion of the food starts by the action of mastication‚ a form of mechanical digestion‚ and the wetting contact of saliva. Saliva‚ a liquid secreted by the salivary glands‚ contains salivary amylase‚ an enzyme

Niageria Lusk ANSC 611.001 August 20‚ 2014 Introduction Digestion is defined as the process by which feed is broken down in the body into a form that can be absorbed and used or excreted. Absorption (a sub-process of digestion) is taking the digested parts of the feed into the bloodstream. The digestive system includes the parts of the body involved in chewing and digesting feed. Essentially‚ during digestion‚ large and complex nutrient molecules are broken down into simpler molecules capable

[pic]Theory notes: Digestion is the process of breaking down organic food into molecules that are small enough to enter cells Chemical digestion : the process of breaking apart complex molecules into simple molecules is called chemical digestion when 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

places that has to do the way we digest and absorb these three macronutrients. The body is like a work line‚ working in an orderly way to make sure digestion and absorption is done properly. Carbohydrates are a primary energy source for our entire body especially the nerve system which means it needs to be digested and absorbed efficiently. Digestion of carbohydrates starts in the mouth where the process of breaking down starch happens and is broken down to maltose. Once it gets to the stomach the

the food we eat and breaking it down to obtain vital nutrients that will allow us to live and be healthy is digestion. According to "Wikipedia.com" (2013)‚ “Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones‚ it is the mechanical and chemical breakdown of food into smaller components that are more easily absorbed into a blood stream” (Digestion). Digestion time varies between individuals and between men and women. After you eat‚ it takes about six to eight hours

During protein digestion‚ a water molecule is added which breaks down the carbonyl-carbon-nitrogen sin the peptide bonds of proteins causing the liberation of amino acids. This process is referred to as proteolysis. Water molecules break down the carbonyl-carbon-nitrogen single bond (peptide bond) that holds single amino acid molecules together (Caroline Ritchie‚ 2013. This process is called hydrolysis and is catalysed by protease. The three main protease enzymes produced during digestion are pepsin
