Lung-tastic Facts
What is the function of the respiratory system?
to exchange oxygen and carbon dioxide
What is the main entry point of oxygen into the body?
Nasal cavity/nose
What gas moves from the blood into the alveoli?
Carbon Dioxide
What dome shaped muscle aids in respiration?
Diaphragm
What is the purpose of the cilia?
the tiny hairs are meant to catch microbes and particles
What gas do we breath in for our cells to use to break down glucose for energy?
Oxygen
What tube carriers air from the pharynx to the lungs?
Trachea
What gas moves from the alveoli to the blood stream?
oxygen
What direction does the diaphragm move when you breath in?
Down
What parts of the respiratory system does the mucous membrane cover?
Everything but the alveolis
What gas is a waste product from cellular respiration?
Carbon Dioxide
What are the two main branches off of the trachea called?
Why is it better to have multiple small alveoli instead of one large alveoli?
More surface area with mulitple smaller alveoli and more surface area=more gas exchange
How far does the diaphragm move up and down?
What is the flap that keeps food and drinks out the trachea?
epiglottis
What is the main organ in the respiratory system?
Lungs
What smaller tubes branch off of the bronchus and leads to the alveoli?
Bronchioles
How many lobes are in the right lung?
3
Which part of your respiratory systems needs air movement to create sound?
Larynx
What is the point in the trachea where it branches into two separate bronchus called?
Carina
How long without oxygen does the brain begin to die?
3-4 minutes
What tiny air sac looks like a cluster of grapes and is the location of the gas exchanged needed to survive?
Alveoli
What are each lobe separated by?
a fissure
Which lung is wider and shorter?
Right
Why does the trachea have rings of cartilage?
Keeps it always open and prevents it from collapsing
