Term Definition
Element A substance that cannot be broken down into simpler substances
Atom The smallest unit of an element w/ that elements properties
Mixture 2 or more elements combined but can be separated by physical means( magnet, filter, dissolve, weight)
Compound 2 or more elements combined that cannot be separated by physical means
Nutrition The intake of food for energy, growth, and repair
Nutrients Raw materials used in the life processes
6 Basic Nutrients Carbohydrates, Vitamins, Minerals, Water, Fats, and Proteins
Calorie The unit of energy
Carbohydrates ( sugars) Primary source of energy- composed of three elements: carbon, hydrogen, and oxygen- organic compound contains both C+H; Methane/ CHh, and Glucose/ C6H12O6- have a ratio of 2H to 1 OXY- examples: glucose, fructose, starch, and cellulose- usually end in -ose
Lipids ( fats) Organic compounds- composed of three elements: carbon, hydrogen, and oxygen- no ratio b/ H+OXY- secondary source of energy- functions: insulation, found in cell membrane- examples: oils, butter, and waxes
Proteins Organic compounds- composed of carbon, hydrogen, oxygen, nitrogen, phosphorous, and sulfur- composed of smaller units called Amino Acids- functions: make pigments, make hormones, make enzymes, repair + building of tissue, and third source of energy
Water Where all the chemical reactions take place
Minerals Aid in bodily processes
Vitamins Aid in bodily processes
Functions of Digestive System Break down food into usable forms: absorb nutrients: remove undigestible materials
Ways of Digestion Mechanical digestion and Chemical digestion
Mechanical Digestion Physical breakdown of food
Chemical Digestion Uses chemicals to break down food
Mouth Intakes food ( ingestion)- mechanical digestion occurs: teeth ( molars- grind, canines- biting, incisors- tearing): tongue pushes food around: saliva is produced by salivary glands; starch ---> disaccharides ( 2 sugar molecules)
Esophagus Connects mouth to stomach- no digestion- peristalsis = wave-like contractions that push food through the digestive tract
Stomach J-shaped- performs mechanical digestion ( churns)- performs chemical digestion: hydrochloric acid ( HCI), mucus = protects the stomach, proteins ---> dipeptides
Small Intestine 22 ft long- performs 2 tasks: chemical digestion is completed: disaccharides ---> glucose: dipeptides ---> amino acids: lipids ---> fatty acid + glycerol- absorption of nutrients: ~~~~ ---> villi ( aid in absorption)
Large Intestine Absorbs water, and forms feces
Rectum Stores feces
Anus Eliminates feces
Accessory Organs Liver, Gall Bladder, Salivary Glands, Pancreas
Liver Produces bile
Bile Mechanically breaks down fat: BIG FAT ---> little fat ( EMULSIFICATION) <--- takes place in small intestine
Gall Bladder Stores fat
Salivary Glands Produce saliva ( contains amylase)
Pancreas Produce enzymes: lipase ---> lipids: peptidase ---> dipeptides: maltase ---> dissacharides
