Document Summary

Absorption: to actually use the nutrients for the body. Accesory organs (food physically doesn"t reach them, instead they release chemicals to the main organs) Within the digestive system, it all breaks down to. The breakdown of these macronutrients is for our body to absorb it and use it to make on our own benefit. When there"s a car outside of the classroom, we have to disassemble it, bring it inside the room, and then assemble it. Bolus: a mix of saliva and food that is broken down in the mouth. To not choke our body has the epiglottis. The esophagus is a canal that makes food travel in a downward motion. Peristalsis: muscles relaxing to be able to make food travel down properly. Sphincter: a small ring of muscle that prevents food from going back up. Has a lot of smooth muscles to make sure that food is being mixed thoroughly.
