Introduction
You are now beginning a study of the Respiratory and Excretion Systems in Chapter 7. It is important that we understand how our bodies work using these systems. These systems in our body have to work together in order to keep us alive and well. You will be exploring the parts of your body by using web resources and answering the questions. You may use the resources on this page, or you may use search engines to find what you’re looking for. Answer each question on your paper with complete sentences and you must "put the question in the answer".
