6. DAILY DOUBLE Respiratory System - 200 The two molecules that travel in opposite directions through the respiratory system What are oxygen and carbon dioxide?

7. Respiratory System - 300 Air enters through nostrils or mouth and moves down this tube What is the Trachea?

8. Respiratory System - 400 The different branches inside the lungs What are bronchi?

9. Respiratory System - 500 A large muscle that controls inhaling and exhaling of the lungs. What is the diaphragm?

10. Digestive System - 100 Digestion using teeth and stomach that physically breaks food into smaller pieces What is mechanical digestion?

11. Digestive System - 200 A muscular tube that connects the mouth to the stomach. What is the esophagus?

12. Digestive System - 300 The organ where most chemical digestion occurs What is the small intestine?

13. Digestive system - 400 The organ that produces bile, then stores it in the gall bladder. What is the liver?

14. Digestive System - 500 The organ that produces 3 digestive enzymes, then delivers the enzymes to the small intestine. What is the pancreas?

15. Circulatory System - 100 The major organ of the circulatory system What is the heart?

16. Circulatory System -200 Specialized cells that transport oxygen and carbon dioxide through the circulatory system. What are red blood cells?

17. Circulatory System - 300 Blood vessels that carry oxygen-rich blood away from the heart What are arteries?

18. DAILY DOUBLE Circulatory System - 400 Circulatory System - 400 DAILY DOUBLE Circulatory System - 400 Circulatory System - 400 Waste product of cells that moves through veins What is carbon dioxide?

19. Circulatory System - 500 Tiny blood vessels that exchange molecules with cells by diffusion. What are capillaries?

20. Systems Connected - 100 Tiny air sacs where carbon dioxide and oxygen exchange between respiratory and circulatory systems. What are alveoli?

21. Systems Connected - 200 Tiny structures inside the small intestine that connects the digestive system to the circulatory system What are villi?

22. Systems Connected - 300 Basic molecule that passes from the villi to the bloodstream What is glucose? (or “nutrients”, or any other type of food molecule)

23. Systems Connected - 400 The process that occurs between glucose and oxygen inside the cell What is Cellular Respiration?

24. Systems Connected - 500 The digestive organ that allows water to be reabsorbed into the bloodstream What is the large intestine?

25. Write a paragraph describing the journey of a carbon dioxide molecule from a cell, all the way until it is exhaled from the body. The molecule must travel through 2 systems. In your explanation, name at least 3 organs for each system. Answers may vary FINAL JEOPARDY!

26. Carbon dioxide diffuses out of the cells and into the capillaries, where it attaches to a red blood cell. It travels through veins on the way to the heart. The heart pumps it back toward the lungs. Carbon dioxide diffuses from capillaries into the alveoli (air sacs) of the lungs. It travels through the bronchi and the trachea, and finally is exhaled from the nose and mouth.
