 Organs in the respiratory
system are the lungs,
mouth, nose, trachea, and
diaphragm. The respiratory
system is involved in the
intake and exchange of
oxygen and carbon dioxide
between an organism and
the environment.

SYSTEM
FUNCTION IN THE
SYSTEM
 In fish and many invertebrates, respiration takes place
through the gills. Other animals, such as insects, have
respiratory systems with very simple features. Plants also
have respiratory systems but the gas exchange can be
opposite to that in animals. The respiratory system in
plants also includes features such as holes on the
undersides of leaves known as stomata.
OTHER SYSTEMS THAT WORK
WITH THIS SYSTEM
 The respiratory system or as in ventilatory system is another name
for it
 It works with the circulatory system
 If the respiratory system did not work properly, a person could
become very ill and may even die
 The ALVEOLI are grouped together like a lot of interlinked caves,
rather than existing as separate individual sacs.
PROCESS OF HOW IT
WORKS
 The respiratory system makes sure that all of the organs receive
nutrients and fresh blood cells. If the respiratory system did not work
properly, a person could become very ill and may even die. The system
works by making the body healthy and keeping all the organs healthy.
The lungs make sure the body has fresh oxygen that is sent to the heart
and all of the other organs in the human body.

LUNGS
 The lungs are the main organs of the respiratory
system. in the oxygen is taken into the body and carbon
dioxide is breathed out . The red blood cells are
responsible for picking up the oxygen to all the body cells,
then pick up the carbon dioxide back to the lungs and we
breathe it out when we exhale
TRACHEA
 The trachea is sometimes called windpipe . The trachea
filters the air we breathe and branches into the bronchi
BRONCHI
 The bronchi are two air tubes that branch off of the
trachea and carry air directly into the lungs
DIAPHRAGM
 Breathing starts with a dome shaped muscle at the bottom of the lungs called the
diaphragm .when you breathe in, the diaphragm contracts it flattens out and pulls
downward . This movement enlarges the space that the lungs are in . This larger space
pulls air into the lungs . When you breathe out the diaphragm expands reducing the
amount of space for the lungs and forcing air out the diaphragm is the main muscle
used in breathing
