Part A
RESPIRATORY SYSTEM
To bring oxygen into your body, and remove the
carbon dioxide from your body, we use the
respiratory system. Your body needs oxygen to
survive.
Part A
5 FUN FACTS
The right lung is slightly larger than the left.
 The breathing rate is faster in children.
 Sneezes travel at about 100 miles per hour.
 Your workout will often make you sneeze.
 Children breathing only through the mouth have
an increased risk at developing a lisp.

Part A
MAJOR ORGANS
Lungs- oxygen is taken in, and carbon dioxide is breathed out through
respiration
Trachea- Also known as the windpipe, the trachea filters the air we
breathe
Bronchi- Air tubes that carry air to the lungs
Diaphragm- It contacts when breathing. It’s a muscle located under
the lungs, and enlarges the space the lungs are in

FUN FACT
Why Do People Yawn?
When someone’s sleepy, they don’t get enough
oxygen when breathing. In response, the brain
makes a person take a long and deep breath; a
yawn.
Part B
Circulatory System:
The Respiratory System is necessary during this
other body system because the blood carries oxygen
around the body which is received by the lungs
during respiration.

Part C
Oxygen enters the nostrils
It goes through the trachea
Into the left & right bronchi
Re-branches into the bronchioles
Lungs inflate with the compression of the
diaphragm
Diaphragm pushes air and lungs deflate, and
CO2 exits the mouth or nostrils
BRONCHITIS

Part C
Bronchitis is the inflammation of the bronchial
tubes, or the pathway that carries oxygen.
Symptoms include wheezing, coughing, and
shortness of breath. Often times, smoking is the
cause of severe bronchitis.
FACT
How asthma works:
Asthma is a chronic disease that affects the lung’s
airways. The band of muscle around them tightens,
reducing the breath. In asthma patients, this is
caused sometimes by irritants, (ex. Smoke) heavy
breathing (often from exercise), or cold weather.
Rescue inhalers make it easier to breathe, but
inhaled steroids are often a daily medication.
Part C
SLIDE #14
A common disease that effects the respiratory
system, is Lung Cancer.
 Lung Cancer can occur in one or both lungs
 Cancer affects the lung cells so that the cells
cannot function properly, which is to carry
oxygen to blood.

Part D
SLIDE #15
The Respiratory system helps the Circulatory
system by moving oxygen throughout the body so
cells can do work
 It also helps the Circulatory remove waste (like
CO2)

SLIDE #16
The average adult with clean lungs can hold his/her
breath for a minute and 30 seconds.
The longest world record for breath holding is held by
Stig Severinsen. He held his breath underwater for 20
minutes and 00 seconds.
