Importance of respiratory and circulatory system in our body

1. Respiratory and Circulatory System

2. STANDARD:
5.L.1.2 Compare the major systems of the human body (digestive, respiratory,
circulatory, muscular, skeletal, and cardiovascular) in terms of their functions
necessary for life
I can explain the functions of the cardiovascular and respiratory systems.
I can identify and explain the relationship between respiratory and circulatory system.
Clear Learning Goals:
Summarize the functions of the respiratory system and list the major parts.
Summarize the functions of the cardiovascular system and list the major parts.
Explain the relationship between respiratory and circulatory (cardiovascular)
system.

3. Respiratory System
• The Respiratory System takes in oxygen from
the air that you breathe.
• It also expels carbon dioxide from your body.

4. Respiratory System
• The lungs are the main structures in this system.

6. Respiratory System
• Air enters your body
through nose or
mouth, moves down
your throat & passes
through the trachea
or windpipe, then to
your lungs.

7. Respiratory System
• Your diaphragm lies below
the lungs.
• The diaphragm is a muscle
that tightens and relaxes to
make you breathe in and
out.

8. Respiratory System
• Oxygen is taken into
your blood and carbon
dioxide leaves your
blood through small
tubes called bronchi
and then tiny air sacs
called alveoli.

14. • Carries oxygen, nutrients &
waste throughout the
body.
• Made up of the heart,
blood vessels and blood.

16. • The heart is the center
of this system, it pumps
blood through blood
vessels called arteries.
• The heart is also called
the cardiovascular
muscle.

17. • Blood moves from arteries to
capillaries.
• In the capillaries oxygen &
nutrients move from the
blood to the body’s cells.
• Blood then moves through
veins back to the heart,
carrying carbon dioxide in it.

20. • The circulatory system
also works with the
respiratory and digestive
systems.

21. • Respiratory system gives oxygen & the
circulatory system takes that oxygen to other
cells.
• Digestive system breaks down nutrients in food
& the circulatory system carries the nutrients
to cells in the body.

22. • The Circulatory System is also sometimes called
the Cardiovascular System.
• Cardio - means heart
• Vascular - means vessels
