Internal structures

Necessary for suvival and growth

Mouth food is ground up into smaller pieces by the teeth. Chewing is the first step in the digestive system. Saliva mixes with food to help soften and break it down.
Esophagus Food travels down this tube to the stomach.
Digestive system Breaks down food into nutrients that are absorbed and used by the body.
Stomach Gastric juices and acids break down the food into nutrients. Food is stored here for 2-4 hours.
Small intestine The broken down food. Moves into the blank, where the nutrients are absorbed in the blood stream. The blank is about 13 feet long.
Large intestine Anything not absorbed moves into the blank. The blank absorbes water and changes the waste from liquid into stool. Eventually, the solid waste is pushed out the body. The blank is about 4 feet long.
Larynx Also known as the voice box - air travels through the mouth into the blank and down the windpipe (trachea) towards the lungs.
Trachea Also known as the windpipe - air flows from the larynx to the blank that splits into two tubes into the lungs.
Lungs Deliver oxygen to your body.
Bronchus As air enters the lungs, it first goes through branches called the blank, then through smaller branches called blank, and finally into the air sacs.
Diaphram Dome shapeed muscle below the lungs and is the main muscle used for breathing.
