Transcript of The Respiratory System
How it functions
Relationship with other systems
Did you know?
Lung cancer is the most common disorder.
Pharyngitis (sore throat)
Others include inflammation, caused by viruses or bacteria.
To move fresh air into the body and get the waste out.
Bring air to the proper body temperature.
Moisturizing the inhaled air to the right humidity.
Protects the body from harmful substances. (coughing, sneezing, swallowing, spitting)
Upper respiratory tract; located outside the chest cavity.
Composed of nose, pharynx, larynx.
Lower respiratory tract; located inside the chest cavity.
Composed of the trachea, lungs, all segments of the bronchial tree including alveoli.
You inhale air through your nose (or mouth) the hairs filter the dust and germs while the air travels down through your pharynx. where it continues down the larynx (which vibrates and allows sound Ex: speech) through the trachea and into the bronchus. Travels into the brochioles into the alveoli. there gas exchange takes place. oxygen is moved to the bloodstream and carried through the body, the oxygen cells are exchanged for carbon dioxide and the bloodstream then carries the waste gas back to the lungs where it is removed from the bloodstream and exhaled from the body. This is called gas exchange.
The right lung is slightly larger than the left.
The surface area of the lungs is roughly the size of a tennis court.
In an adult, each lung weighs about 1lb.
Chest movement during breathing isn't the result of air movement.
Sneezes travel up to 10mph~ 2013 journal PLOS ONE
Lungs are the only organs that can float on water.
Women have a faster breathing rate.
At rest we breathe about 12 to 15 times a minute. (17,000 a day, over 6 million a year)
At rest; we exhale up to .59fl oz of water per hour and four times that when you exercise~2012 article in the journal Polish Pneumonology and Allerology.

Stacks. Makin bank with that rich 02 and through the body. Helps you feel good. Lets you live hood, naw. Bring you a clearer view. Take care of your respiratory system. Think with your head.
