The systems within the body work together to keep the body functioning. Eating healthful foods, staying active, and drinking plenty of water help to maintain the body systems. Good hygiene and regular hand washing can prevent diseases and help keep the body healthy. A healthy body is better able to regulate itself and to return to a normal state during times of stress or illness.
Set some goals for learning about human body systems by creating a three-column chart. In the first column list each body system covered in this chapter. Write a question you have about each body system in the second column. As you read, look for an answer to your question or conduct additional research and record your answer in the third column.
