|What are the five main food groups?||Dairy, Meat, Vegetable, Fruit, Bread|
|Name three things a food label tells you?||Calories, carbohydrates, fat|
|How do you find out what is the largest ingredient in a food?||The ingredient that comes first|
|What does serving size on a label mean?||It says what and how much your are eating.|
|Name two common diseases of the digestive system?||Constipation and Diarrhea|
|What is the purpose of the digestive system?||A collection of organs that work together to breakdown food so that it can be used by the body.|
|List the path that food takes through the digestive "tract"||Mouth, Throat, esophagus, stomach, large intestine, small intestine, anus|
|Does food travel through the liver, pancreas and gall bladder?||No. Liver makes bile which is stored in the liver which is used to breakdown food in the stomach. Pancreas is a fish shaped organ that makes pancreatic juice that is made up of digestive enzymes and bicarbonate to neutralize acid in the intestine|
|What is the difference between mechanical and chemical digestion?||Mechanical breaks food into smaller pieces, chewing. Chemical attacks food with enzymes to break it apart it nutrients and help the body absorb it.|
|Explain how mechanical AND chemical digestion takes place in the mouth?||Food enters the body through the mouth, chewing occurs, and saliva starts to break it down and help lubricate it to be swallowed.|
|What are enzymes?||569. Enzymes are special substances that break down nutrients into smaller particles that the body can use. They break it down into proteins.|
|Where are enzymes found in the digestive system?||Enzymes are chemicals that help breakdown food into nutrients.|
|What is peristalsis?||Peristalsis is the process by which the esophagus squeezes the mass of food with "rhythmic muscle contractions".|
|What is the function of the gallbladder?||The Gall bladder temporarily stores bile and secretes it into the small intestine.|
|What are the functions of the liver?||1. Makes bile which breaks down fat. It is stored in the ball bladder.
2. Stores nutrients.
3. Breaks down toxic substances in blood.
4. Makes cholesterol for cell membranes
|What are the functions of the pancreas?||1. Secretes more enzymes into the small intestine and absorbs nutrients.
2. Creates bicarbonate which helps neutralize acid.
3. regulates blood sugar by secreting insulin.
|What happens to food once it is in the stomach?||1. Continues mechanical digestion.
2. Enzymes and acids help chemically digest food.
3. Acid environment helps kill bacteria.
4. Food is reduced to chime – Soupy mixture of digested food.
|Once the chime is in the small intestines, what happens to the nutrients? What happens to waste?||Chime/chime is a mixture or broken down food/soupy mixture in the stomach. It is slowly released into the small intestine where it is mixed with digestive fluids.|
|How do villi help your cells?||Villi are small finger like projections from in the small intestine. They are covered with tiny nutrient-absorbing cells that help nutrients into the body.|
|What are the main organs of the digestive system:||Mouth, stomach, small intestine, large intestine.|
|what is saliva?||It is a chemical that mixes with food in your mouth. It contains a chemical that can change starch into sugar. The it can be absorbed into blood.|
|The body gets it raw materials from food by the process of____||digestion|
|Food enters your body through the?||mouth|
|The liquid in your mouth is called||Saliva|
|Saliva contains a chemical that changes starch into ____||sugar|
|Digestion is the breaking down of food into||nutrients|
|In what order does this process take place in the digestive system? 1, 2, 3, or 4 Food is mixed with chemicals||2|
|In what order does this process take place in the digestive system? 1, 2, 3, or 4 Nutrients from the food go into the blood.||3|
|In what order does this process take place in the digestive system? 1, 2, 3, or 4 Food is ground up||1|
|In what order does this process take place in the digestive system? 1, 2, 3, or 4 The unused part of food is sent out of the body.||4|
