Final Filled-In Passage:



> All living things need 11, the energy the body needs comes from the 10 it eats. The parts of the body that help break down the food it eats and turn it into 4 for the body is called the digestive system. The digestive system is responsible for digesting food to 2 all of the 14 in the body. Digesting food begins at the time food is put into the 5. Digesting takes two forms, mechanical and 6. Your mouth does the chewing which is referred to as mechanical digestion and your 3 and intestines break the food down using chemicals turning it into 4 which is called chemical digestion.

From the small intestine, the nutrients reach the blood stream by 13 where they nourish the cells in the body. What is left over then travels to the large intestine where most of the water is removed from the food. What remains is then turned into solid 8 to be taken to the rectum for excretion.
