2.2 The Digestive and Excretory Systems


 * 2.2 Introduction** p 64

paragraph: Our bodies need nutrients that can be found in most foods we eat. We require carbohydrates, proteins, fats, vitamins, and minerals, to keep ourselves moving in the day. We use our digestive system to make these nutrients into chemicals that our body can use as energy. The nutrients we eat go through a four step process, ingesting, digesting, absorbing and eliminating. If our bodies do not get enough nutrients, through eating disorders, our digestive systems will not function properly and will not be able to send energy to the rest of the body. Diets, which are balanced meals, help us eat proper portionsof different types of food to maintain our health.
