1. Science Sponge / List the accessory organs of the digestive system and its functions.

2. Science Sponge / What blood vessel is responsible for taking blood to the heart? / What kind of bone allows for flexible movement and stress? / What does the lymphatic system do? / What blood vessel is responsible for taking blood to the heart? / What kind of bone allows for flexible movement and stress? / What does the lymphatic system do?

3. Science Sponge / This is the process for food being led to the stomach. What is it? / The chemical that mixes with your food in the stomach / This is the process for food being led to the stomach. What is it? / The chemical that mixes with your food in the stomach

4. Science Sponge / List three things that you know about the blood, such as parts of the blood, the places where blood cells form, and the function of blood throughout the body.

6. Parts of the Digestive System / Mouth / Pharynx / Esophagus / stomach / small intestine / large intestine / Colon-rectum / anus / Mouth / Pharynx / Esophagus / stomach / small intestine / large intestine / Colon-rectum / anus

7. Accessory Parts / Accessory Organs / Salivary Glands / Pancreas / Liver and Gallbladder / Accessory Organs / Salivary Glands / Pancreas / Liver and Gallbladder

9. Process--Mouth / Food enters the mouth (mechanical disgetion) / Teeth grind, tear and chop food / Saliva moistens it / Amylase begins to break down carbs in food / Soft mass of chewed food--BOLUS / Food enters the mouth (mechanical disgetion) / Teeth grind, tear and chop food / Saliva moistens it / Amylase begins to break down carbs in food / Soft mass of chewed food--BOLUS

10. Swallowing / Swallowing--muscles in the tongue and mouth push food into….. / Esophagus--epiglottis keeps most food out of the windpipe / Connects to the stomach at the pyloric valve / Peristalsis forces food into stomach / Swallowing--muscles in the tongue and mouth push food into….. / Esophagus--epiglottis keeps most food out of the windpipe / Connects to the stomach at the pyloric valve / Peristalsis forces food into stomach

11. Stomach / Stomach--churns and mixes food with acids and enzymes / Three mechanical/chemical tasks / Storage / Mix food, liquid and digestive juices / Soup like mass called CHYME / Empty contents slowly into small intestine / Stomach--churns and mixes food with acids and enzymes / Three mechanical/chemical tasks / Storage / Mix food, liquid and digestive juices / Soup like mass called CHYME / Empty contents slowly into small intestine

12. Small Intestine / Pyloric sphincter allows chyme into duodenum / Bile from pancreas added / Digestion continues / Absorption begins / Villi--finger like projections / Pyloric sphincter allows chyme into duodenum / Bile from pancreas added / Digestion continues / Absorption begins / Villi--finger like projections

13. Role of Accessory Organs / Liver--produces bile to help absorb fat; processes nutrients / Gallbladder--stores bile / Pancreas--produces enzymes; neutralizes stomach acids / Liver--produces bile to help absorb fat; processes nutrients / Gallbladder--stores bile / Pancreas--produces enzymes; neutralizes stomach acids

14. Large Intestine / Main function--remove water from undigested matter and form solid wastes / Colon--solid wastes are stored until expelled through the rectum / Main function--remove water from undigested matter and form solid wastes / Colon--solid wastes are stored until expelled through the rectum

16. Urinary System Contains organs that remove waste products from your blood Three body systems have a role in excretion: integumentary, respiratory, and finally the urinary system. Contains organs that remove waste products from your blood Three body systems have a role in excretion: integumentary, respiratory, and finally the urinary system.

17. Lungs / Remove carbon dioxide and water vapor

18. Skin / Blood flows through vessels of the skin / Water, salt and other wastes diffuse through the sweat glands / Solid wastes stay on the skin / Liquids evaporate and cool the body / Blood flows through vessels of the skin / Water, salt and other wastes diffuse through the sweat glands / Solid wastes stay on the skin / Liquids evaporate and cool the body

19. Kidneys / Located on either side of backbone / Filters waste from other body systems / Makes sugar available as fuel and sends it to tissues / Removes toxic chemicals in the bloodstream / Located on either side of backbone / Filters waste from other body systems / Makes sugar available as fuel and sends it to tissues / Removes toxic chemicals in the bloodstream

20. Kidneys / Blood circulates collecting waste / Enters kidneys / Reaches NEPHRONS--filtering units / Remove excess water, salt and urea from blood / Material left in nephron is urine / Passes into 2 tubes called URETERS which connect to urinary bladder / Urine passes through URETHRA--and out / Blood circulates collecting waste / Enters kidneys / Reaches NEPHRONS--filtering units / Remove excess water, salt and urea from blood / Material left in nephron is urine / Passes into 2 tubes called URETERS which connect to urinary bladder / Urine passes through URETHRA--and out

21. Urinary System Problems / Bacterial infections: infections can get into the bladder, and cause painful infections / Kidney stones: salts and wastes collect inside the kidneys and form kidney stones / Bacterial infections: infections can get into the bladder, and cause painful infections / Kidney stones: salts and wastes collect inside the kidneys and form kidney stones

22. Urinary System Problems / Kidney disease: damage to nephrons prevent normal kidney functioning, a person will end up on dialysis to help filter the blood.
