Your other body systems help your bones, muscles, and
skin do their jobs.
Your digestive system provides the nutrients that the
cells in your bones, muscles, and skin need in order to
grow and repair themselves.
• Your respiratory system provides oxygen to keep the cells
in your bones, muscles, and skin healthy and growing.
• Your circulatory system carries nutrients and oxygen to
the cells in your bones, muscles, and skin. It also carries
wastes away from these cells.
•
This page describes
how your digestive,
respiratory, and
circulatory systems help
your bones, muscles,
and skin do their jobs.
Before you read, write
three questions that
you should be able to
answer after reading.
1. • Write the following words in circles on a page in your
notebook:
- digestive system
- respiratory system
- circulatory system
- muscular system
- skeletal system
- skin
• Draw a line from the digestive system to any other circle it
is connected to. On the line, write how the two circles are
connected. Do the same for the other circles. You only need
to have one line from each circle, but you might want to
have more.
