Small intestines | The organ where most of the chemical digestion of food takes place, nutrients from food are also absorbed here |

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 |

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 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 |
