Respiratory and Circulatory
Systems
Respiratory System
• Takes in oxygen from the air that you breathe.
• Lungs are the main structures in this system.
Respiratory System
• Air enters your body through the nose or
mouth , moves down your throat and passes
through the treachea or windpipe, then to
your lungs.
Respiratory System
• Oxygen is taken into your blood and carbon
dioxide leaves your blood.
• You diaphragm lies below the lungs. The
diaphragm and muscles around it tighten
(contract) and relax (extend) to make you
breathe in and out.
Circulatory system
• Carries oxygen,
nutrients, and waste
throughout the body
• Made up of the
heart, blood vessels,
and blood
Circulatory System
• The heart is the
center of this system,
it pumps blood
through blood
vessels called
arteries.
• The hear is also
called the
cardiovascular
muscle.
Circulatory System
• Blood moves from
arteries into
capillaries.
• In the capillaries
oxygen and nutrients
move from the blood
to the body’s cells
• Blood then moves
through veins back to
the heart, carrying
carbon dioxide in it.
Circulatory System
• The circulatory
system also works
directly with the
respiratory and
digestive systems
Circulatory System
• Respiratory system gives oxygen and the
circulatory system takes the oxygen to other
cells.
• Digestive system breaks down nutrients in
food and the circulatory system carries the
nutrients to cells in the body.
