A defective gene causes a thick, buildup of mucus in the lungs, pancreas and other organs. In the lungs, the mucus clogs the airways and traps bacteria leading to infections, extensive lung damage and eventually, respiratory failure.
Cystic Fibrosis
The part of the respiratory system that is connected to the nose and mouth and is shared with the digestive system.
Pharynx
As we exhale, the muscles in our diaphragm and along our rib cage do what?
The muscles relax
the diaphragm contracts during _____________
Inhalation
The chemical reaction where glucose and oxygen are consumed and carbon dioxide and water are produced into ATP?
Cellular respiration
chronic respiratory disease causing bronchial inflammation, fever, coughing, green mucus, and is usually caused by a VIRUS
bronchitis
True or False: Diffusion of gases happens in the alveoli.
TRUE
The trachea is lined with rings of this flexible connective tissue. These rings help keep it sturdy and protected
Cartilage
What are the jobs of the respiratory system?
to deliver oxygen and remove carbon dioxide
alveoli, emphysema
The harmful, uncontrolled growth of cells in the lungs causing tumor and damaging growths. It is a leading cause of deaths worldwide.
lung cancer
Commonly called the windpipe, this structure is strengthened by rings of cartilage.
trachea
name the three pharynx and where located
oropharynx-the part of the pharynx between the soft palate and the upper edge of the epiglottis
nasopharynx-behind nasal cavity, connects nasal cavity to the top of throat, l
laryngopharynx-extending from the hyoid bone to the esophagus.
The condition where a person's airways become inflamed, narrow, and swollen, and extra mucus is produced due to TRIGGERS?
asthma
What is the main organ or organs of the respiratory system? Explain some properties they have
2 lungs, left has 2 lobes, right has 3 lobes
Smoking affects the oxygen in our blood how?
carbon monoxide binds to hemoglobin making it hard for oxygen to get into cells
These air passages split at the bottom of the trachea and go into the lungs (the first split, be specific)
primary bronchi
What are the smaller air passages that branch off each bronchi within the lungs?
Bronchioles
The movement of air in and out of the lungs is called?
breathing or ventilation
what gas is exchanged from the capillaries to the alveoli?
carbon dioxide
CO2
What is the hollow muscular organ forming an air passage to the lungs and holding the vocal chords?
larynx
tiny balloon-like sacs where gas exchange occurs
Alveoli
This is a flap that covers the windpipe and helps keep food and water from entering the lungs.
Epiglottis
List the correct order of air flow into the respiratory system. You should have at least 5 words listed.
nose or nasal cavity, pharynx, epiglottis, larynx, trachea, bronchi, bronchioles, alveoli

Toxic substance found in cigarettes that causes lung tissue to die, causes severe damage by destroying cilia, leads to lung cancer and other respiratory conditions.
What is the primary addictive component in cigarettes
Tar, nicotine
The tube that connects your upper respiratory and lower respiratory systems
Trachea
Another name for the voice box is:
Larynx

What are the structures at the end of the bronchioles that look like bunches of grapes, surrounded by capillaries? What takes place here?
alveoli, diffusion takes place there or exchange of oxygen and carbon dioxide
