1 Digestive System Science 7 HMS 2016

2 ??? What is the role of the digestive system?

3 1. Breaks down food into molecules the body can use 2. Molecules are absorbed into the blood stream to be carried to the cells 3. Wastes are eliminated from the body What is the role of the digestive system?

4 ??? The digestive system obtains food from energy by

5 Chemical Digestion Mechanical Digestion absorption/diffusion The digestive system obtains food from energy by

6 ??? Which term describes the smooth muscle contractions that push food down the esophagus?

7 peristalsis Which term describes the smooth muscle contractions that push food down the esophagus?

8 ??? Which term describes the chemical that digest specific food molecules (carbohydrates, proteins, and fats) into usable nutrients?

9 enzyme Which term describes the chemical that digest specific food molecules (carbohydrates, proteins, and fats) into usable nutrients?

20 ??? A long, muscular tube that squeezes food down into the stomach

21 esophagus A long, muscular tube that squeezes food down into the stomach

22 ??? Helps continue breakdown of food by adding digestive juices to the small intestine

23 pancreas Helps continue breakdown of food by adding digestive juices to the small intestine

24 ??? Digestion is completed here and most nutrients are absorbed into the blood stream

25 Small intestine Digestion is completed here and most nutrients are absorbed into the blood stream

26 ??? Teeth grind and chew; saliva moistens and begins chemical breakdown

27 mouth Teeth grind and chew; saliva moistens and begins chemical breakdown

28 ??? Also know as colon ; takes up any leftover vitamins, minerals, and water; rectum stores waste before eliminating through anus

29 Large intestine Also know as colon ; takes up any leftover vitamins, minerals, and water; rectum stores waste before eliminating through anus

30 ??? Stores bile made in the liver

31 Gall bladder Stores bile made in the liver

32 ??? J-shaped organ that digests food using muscle contractions and powerful acids and enzymes

33 stomach J-shaped organ that digests food using muscle contractions and powerful acids and enzymes
