| mouth | Begins to break down food into smaller pieces through mechanical digestion |
| saliva | starts the process of chemical digestion in the mouth |
| esophagus | The transport tube that carries chewed food to the stomach |
| Stomach | Continues the process of mechanical digestion and secretes gastric juices that continue the process of chemical digestion started in the mouth |
| Small intestines | The organ where most of the chemical digestion of food takes place, nutrients from food are also absorbed here |
| Large intestines | The organ where water is absorbed from the food and taken into the bloodstream & prepares the remaining undigested food for elimination from the body |
| Rectum | a short tube that stores solid waste until it is eliminated from the body through the anus. |
| Liver | A secondary organ of the digestive system that produces bile |
| bile | used by the body to break up fat particles |
| Gallbladder | A secondary organ to the digestive system that functions to store bile produced by the liver |
| Pancreas | A secondary organ to the digestive system that functions to produce digestive juices that help to further break down the food in the small intestine |
| Kidneys | get rid of urea, excess water, and some other waste materials released by the cells |
| urine | is composed of urea, excess water, and other waste materials filtered by the kidneys |
| Ureters | Tubes which connect each kidney to the bladder |
| Bladder | A saclike muscular organ which stores urine until it is released from the body |
| Urethra | Tube through which urine passes before it is removed from the body |
| Function of the Digestive System | to breakdown foods into nutrients that can be used by the body, absorb nutrients that are necessary for energy, growth, and maintenance, and rid the body of solid wastes |
| Functions of the Excretory System | to filter out cellular wastes, toxins, and excess water that result from cellular respiration. |
| toxins | chemicals that could be poisonous to the body |
| smooth muscle | controls movement of materials through the digestive system |
| The digestive system works with the _______ system to make sure that nutrients made available by digestion get to the cells of the body | circulatory system |
| The circulatory system works with the excretory system to help remove ______ from the body | wastes |
| Path of food through digestive system | mouth,esophagus,stomach,small intestine,large intestine |
| Path of urine through excretory system | kidneys,ureter,bladder,urethra |
| anus | part of the digestive system where elimination of indigestible solid materials takes place |
| kidneys act to ______ wastes from the bloodstream | filter |
