What is the respiratory system and what does it do? The respiratory system is a body system that is responsible for performing the task of getting oxygen into the body and removing carbon dioxide and water from the body.
1. What is the respiratory system and what does it do?The
respiratory system is a body system that is responsible for
performing thetask of getting oxygen into the body and removing
carbon dioxide and water from the body.
2. Organs of the system and their functions: Nose and mouth:
oxygen enters. Trachea(wind pipe): tube that enters chest cavity
and splits into 2 smaller tubes called bronchi. Epiglottis: flap
that opens to let air in ; keeps food out. Lungs: bronchial tubes
that divide into smaller tubes which connect to tiny sacs called
alveoli. Diaphragm: a muscle that pumps carbon dioxide out of lungs
and pulls oxygen into the lungs.
3. Connections to other systems Rib cage protects the lungs -
Skeletal system Diaphragm, a muscle - Muscular system Epiglottis
keeps food out - Digestion system Lungs, where oxygen is picked up
by blood - Circulatory system
4. Possible diseases that can affect this system: Asthma a
disorder that is controllable, but not curable that causes airways
of lungs to swollen and narrow bleeding to wheezing, shortness of
breath, chest tightness, and coughing. Pneumonia a breathing
condition infection of the lungs, that creates a fluid and mucus
that blocks the alveoli. Bronchitis the condition in which the
lining of the bronchial tubes becomes inflamed or infected. Lung
cancer - occurs when this uncontrolled cell growth begins in one or
both lungs. Common Cold is an infection of the nose, nasal
passages, and the throat.
5. The steps of how the system works when inhaling:1) The
diaphragm contracts and flattens out so lungs have more room to
grow larger as they fill up with air.2) At the same time, we inhale
air through mouth and nose3) Air goes through the wind pipe or
trachea.4) On the way down the windpipe, tiny hairs called cilia
move gently to keep mucus and dirt out of the lungs.5) Air goes
through the series of branches in your lungs, through the bronchi
and bronchioles.6) Air ends up in the alveoli which fills up with
air, and then the lungs get bigger.
6. The steps of how the system works when exhaling:1) The
diaphragm relaxes and moves up, pushing air out of the lungs.2) Rib
muscles become relaxed, and your ribs move in again, creating a
small space in your chest.3) By now, the cells have used the oxygen
they need, and your blood is carrying carbon dioxide and other
wastes that must leave your body.4) The blood comes back through
the blood vessels, or capillaries and wastes enter the alveoli.5)
Then you breathe out the carbon dioxide in the reverse order of how
they came in the air goes through the bronchioles, out the bronchi,
out of the trachea, and finally out through the mouth and
nose.
7. What systems would not function without the respiratory
system? Digestive system: muscles can not function without oxygen ;
no way to push down food. Cardiovascular: the heart can not pump
with out oxygen and deliver blood to the body.
8. Interesting Facts about the respiratory system.. The left
lung is smaller than the right lung to provide space for the heart.
The sneezing rate/speed record is 165 km per hour. The breathing
rate is faster in children and woman than in men.
