Mechanical and chemical actions required to reduce foods into absorbable substances to be assimilated by the body. Mechanical action begins in the mouth with the chewing of foods and continues throughout the digestive process by the churning action of the gastrointestinal organs. Chemical digestion also\u00a0begins in the mouth and continues in the stomach and finally in the small intestine. The chemicals of digestion are called enzymes.<\/p>\n
The process by which food is broken down in the alimentary canal into components which can be absorbed by the body.<\/p>\n
The process by which the body takes food and breaks it down into smaller components to be used by the body. Proteins are broken down into amino acids, carbohydrates into simple sugars, and fats into fatty acids.<\/p>\n
The process of mechanical and chemical breakdown of food into absorbable units within the digestive tract.<\/p>\n
The process of breaking down food in preparation for absorption is called digestion. While a portion of digestion includes chewing food, lubricating food with saliva, and grinding food within the stomach, complete digestion requires enzymatic or chemical digestion of nutrients in foods, such as macronutrients. This type of digestion occurs primarily in the small intestine. Overall, chemical digestion in the stomach is primarily limited to the actions of HC1, which denatures protein, and pepsin, which is responsible for breaking protein down into smaller polypeptide units. Within the small intestine, chemical digestion is accomplished by many digestive enzymes produced in the pancreas or by the small intestine itself.<\/p>\n
Process of breaking down food, by mechanical (e.g., chewing, churning) and chemical (e.g., the action of enzymes) means, into substances that can be absorbed and used by the body. Chemical digestion begins in the mouth with the action of saliva but takes place largely in the stomach and small intestine.<\/p>\n
The process by which the body converts food into materials that can be absorbed in the intestines. The digestive system comprises about half the body’s internal organs. In digestion, a wide variety of complex plant and animal food sources are broken down into their basic chemical units. The digestive tract, is a series of joined and coiled tubes that extends from the mouth to the esophagus, stomach, small and large intestines, rectum, and anus. Food is propelled through the digestive tract by a rhythmic series of muscular contractions called peristalsis.<\/p>\n
The three processes by which the body incorporates food are digestion, absorption, and assimilation. In digestion, food is softened and converted into a form soluble in the watery fluids of the body; or, in the case of fat, into minute globules. The substances formed are then absorbed from the intestines and carried throughout the body by the blood. In assimilation, these substances, deposited from the blood, are used by the various tissues for their growth and repair.<\/p>\n
The process by which food is broken down mechanically and chemically in the gastrointestinal tract and converted into absorbable forms. Salts (minerals), water, and monosaccharides can be absorbed unchanged, but starches, fats, and proteins must be broken down into smaller molecules. This is brought about by enzymes, each of which acts on a specific type of food and requires a specific pH to be effective.<\/p>\n
The assimilation of food by the body. Waste products the body cannot use leave the body through bowel movements.<\/p>\n
The process by which the nutrients in food are broken down into a form the body can absorb and use.<\/p>\n
With rare exceptions, most foods cannot be directly absorbed into the bloodstream. Instead, they must undergo a process of physical breakdown, resulting in a soft mass, followed by chemical decomposition using digestive juices. This process ultimately produces soluble products that are capable of permeating the intestinal walls and entering the bloodstream. However, indigestible components, including cellulose, skin, seeds, coarse fibers, and other materials in fruits and vegetables, are separated and ultimately excreted from the body.<\/p>\n
The intricate orchestration of mechanical, chemical, and enzymatic processes transforms food into the essential substances that can be effectively utilized by the human body.<\/p>\n
The process of digestion involves the breakdown of food into smaller constituents that can be easily transported and utilized by the body. Through this intricate process, the nutrients present in food are broken down into simpler forms, allowing for their absorption and subsequent utilization by the body’s cells and tissues.<\/p>\n
The chemical transformations that food undergoes before being absorbed from the intestine for utilization as energy by the body.<\/p>\n
