Respiratory System
These are hollow areas in your head. They warm, moisturize and filter air.
Sinus cavities/Nasal cavities
What is the name of the large muscle that pulls air into the lungs?
The diaphragm
This is damage to the alveoli causing shortness of breath.
This is a chemical reactions where glucose and oxygen are consumed and carbon dioxide and water are produced.
What are three reasons why you shouldn't pick your nose?
1. You spread your germs to others 2. You transfer germs from your fingers to your nose 3. You can easily break the skin in you nose
The part of the respiratory system that is connected to the nose and mouth and is shared with the digestive system.
Pharynx
What is the main organ of the respiratory system?
Lungs
What is bronchitis?
Bronchitis is the inflammation of the bronchial tubes, causing people to cough up thick mucus.
Name three things that nose hairs do.
1. Keep large items out of the nose 2. Warm the air going in 3. Moisten the air going in
Cells consume this during respiration.
Oxygen
True or False: Diffusion happens in the alveoli.
TRUE
What is the large tube that connect the larynx to the bronchi?
The trachea
This is a condition in which the body fails to filter the air and people develop a lung infection.
pneumonia
What are the tiny hairs that move back and forth along the trachea called?
Cilia
True or False: The tar in cigarettes causes lung cells to die?
TRUE
Commonly called the windpipe, this structure is strengthened by rings of cartilage.
trachea
What are the two tubes that lead from the bottom of the trachea to each lung?
The bronchi
What is asthma?
A tightening and thickening of the bronchial tubes, making the air passages inflamed and hard to breathe.
This happens when something irritates your nose
Sneeze
Physical activity causes breathing rate to do what?
Increase
These air passages diverge from the windpipe at the bottom of the trachea.
bronchi
What are the smaller air passages that branch off each bronchi within the lungs?
Bronchioles
What is lung cancer?
A harmful proliferation (growth) of cells in the lungs causing tumors and damaging growths.
This happens when something irritates your throat or airways
Cough
During inhalation what does the diaphragm do?
It contracts or flattens.
What is a job of the respiratory system?
To deliver oxygen to the bloodstream. To remove waste.
This is a flap that covers the windpipe and helps keep food and water from entering the lungs.
Epiglotis
What is the number one cause of lung disease/damage?
Smoking
What is breathing?
It is the movement of air in and out of your lungs. It is a physical process.
What is secondhand smoke?
You are not smoking, but you breath in the smoke or vapor from someone who is smoking
The hollow muscular organ forming an air passage to the lungs and holding the vocal chords.
larynx
What are the tiny balloon-like sacs that look like bunches of grapes where carbon dioxide in the blood is exchanged for oxygen?
Alveoli
What is the addictive substance found in cigarettes?
Nicotine
List in order from inhalation what the pathway of air is:
1. nasal cavity/mouth 2. pharynx 3. larynx 4. trachea 5. bronchi 6. bronchioles 7. alveoli 8. exhalation
What can smoking do to your lungs?
1. Build up tar 2. Reduces lung capacity 3. Causes cancer
