The Important Thing
About the Human Body
The important thing about our
bodies is that all parts work
together.
The circulatory system
receives oxygen from the
respiratory system.
Respiration is the intake
of oxygen from the air
into my body through two
specialized organs called
the lungs. When my lungs
are filled with air, oxygen
is absorbed into the
bloodstream through tiny
sacs called alveoli.
Carbon dioxide passes
from the blood into the
alveoli and is flushed out
of the body when I
exhale. But, the
respiratory system
cannot work alone…

The respiratory system
receives nutrients from the
digestive system. This is a
tube of connected organs
where specialized activities
occur along its length. This
begins in the mouth where my
food is chewed and mixed
with saliva. The process of
digestion continues after the
food is swallowed and enters
my stomach. Then my
intestines can absorb
digested food. But, the
digestive system cannot work
alone…

The waste from the
digestive system is
removed from my
body by the
excretory system.
The kidneys process
cell waste, including
carbon dioxide and
ammonia. Waste is
removed from my
body through urine
and feces.
