Notes: The Respiratory System
Function #1: Get _____________ from the environment and remove ____________________
o Air enters your body when you _________________
o _______________ is transported to your cells through the ___________________ system
o Carbon dioxide and other _____________ gases exit your body when you _____________
o Proper levels of _______________ and carbon dioxide in your ___________ are essential
o IF levels of oxygen or carbon dioxide _____________, your brain or blood vessels will
signal the body to breathe ______________ or slower
Function #2 – _____________________________
o Examples – _________________, singing, sighing, laughing, etc.
o Air ______________ over your vocal cords allows you to produce ____________
o The _______________ in your throat, mouth, cheeks, and lips, allow you to form sound
into words
Function #3 – __________________ / keeping out harmful materials
o __________________, coughing, etc.
Happens in your ___________ – not just ___________________________ system!
Uses ________________ in chemical reactions that release _________________
Respiratory system works with the ____________________ and ________________________
systems to make this possible
________________________________ and water are ____________ products of this process
Throat (Pharynx)
o Passage between ____________ and trachea
o _______________ also passes through the throat
Trachea
o ___________-like structure
o Also called the _____________ pipe
o Surrounded by ________________________ rings that keep the tube open
Epiglottis – flexible flap of cartilage
o In the ______________ - closes over the trachea when you swallow
o Prevents food and liquids from entering the _____________
Larynx / vocal cords
o Sometimes called the _______________ box
o Found in your neck at the top of your _________________
o Vocal cords are folds of ______________ in the larynx – they contract/relax and air
moves over them to produce _____________.
Lungs
o Two large organs located on either side of your ________________
o Contain ______________
Bronchial tubes or bronchi
o Carry _____________ into each lung
o Branch throughout the lungs into ________________ and smaller ____________
Alveoli
o Found in the lungs at the ____________ of the ___________________ bronchial tubes
o Tiny air __________ – air enters
o Only _________________________ thick
o Collect ________________ and exchange it with __________________________
Diaphragm
o Large _____________ that stretches across the floor of the chest cavity under your lungs
o When you inhale, your diaphragm ______________ and pulls down
o When you exhale, your diaphragm and other muscles ____________
Tissues in the bronchial tubes _____________ and muscles spasm, making airways _________
The person can’t get air into or out of the lungs _______________
This reduces the amount of ________________ entering the blood stream
