• Digestive system


  The process that is responsible for breaking down food into smaller pieces that the body can use energy and nutrients to survive
• Ingestion


  Taking food and liquids into the body through the mouth
• Digestion


  Breaking down food into smaller, simpler molecules that can be absorbed and used by the body
• Peristalsis


  A series of wave-like muscle contractions that pushes and transport foods and liquids to the stomach
• Stomach


  • J-shaped and bag-like that secretes gastric juices including hydrochloric acid and pepsin
• Absorption


  Occurs primarily in the small intestines, where nutrients from the digested food are absorbed into the bloodstream for distribution to cells throughout the body
• Villi


  • Tiny and finger-like projections that contains blood capillaries
• Assimilation


  Process by which absorbed nutrients are incorporated into the cells and tissues of the body for use
• Small intestines


  • Absorbs the nutrients and gets rid of the unnecessary components from the foods
• Large intestines


  • Completes absorption and compacts waste
• Rectum


  • Holds the poop or feces until it's time to release and it will now push out through the anus
