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.
Internal respiration exchanges gases between _ and _.
blood and body cells
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 the inflammation of the bronchial tubes, causing people to cough up thick mucus?
bronchitis
Name three things that happen in the nasal cavity.
1. Keep large items out of the nose 2. Warm the air going in 3. Moisten the air going in
What is the amount of air that doesn't leave body until death?
residual volume
What do you call the lining around the lungs?
pleura
Pulmonary ventilation exchanges gases between what two places?
outside air and lungs
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
What is the trigger for inhalation?
too much carbon dioxide in blood
Commonly called the windpipe, this structure is strengthened by rings of cartilage.
trachea
What is the term for the exchange of gas between the alveoli and the bloodstream?
external respiration
What is a tightening and thickening of the bronchial tubes, making the air passages inflamed and hard to breathe?
asthma
This happens when something irritates your nose
Sneeze
Which part of brain stem controls basic breathing rate?
medulla oblongata
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
How does smoking lead to things getting into your lungs that shouldn't get there?
It paralyzes the cilia
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 the greatest volume of air that can be exchanged between lungs and atmosphere while still alive?
vital capacity
What instrument is used to measure lung capacities?
spirometer
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 part of your brainstem that controls intensity of breathing?
pons
