In Section 2, you will investigate the systems inside the
body. You will explore the respiratory, circulatory,
digestive, and excretory systems that keep our bodies
working. You will learn about the major organs in each of
these systems and how the systems work. The lessons
emphasize how each of these systems is connected to the
others and that they all work together as a team so the body
can meet its basic needs for life.
Throughout the section, you will find Great Scientist
profiles, A Closer Look and Imagine features, as well as
optional Internet Links.
