|---|---|
| nutrient | substances that provide raw materials and energy to the body to carry out functions |
| fat | high energy nutrients made of carbon, oxygen, and hydrogen |
| mineral | nutrients not produced by animals that the body needs in small amounts |
| epiglottis | flap of tissue that prevents food from going into the windpipe |
| small intestine | where most chemical digestion takes place |
| villus | small finger like organisms in the inner small intestine and provide the surface area where digested food is absorbed |

| carbohydrates | energy rich organic compounds that are made of carbon, oxygen, and hydrogen |
| protein | nutrients that contain nitrogen, carbon, and oxygen that help with tissue growth and repair |
