What is the Adam's Apple?
The leaf like structure that closes over the windpipe when we eat and drink to prevent food and water from entering our lungs.
What is the epiglottis?
Two spongy, saclike respiratory organs in most vertebrates, occupying the chest cavity together with the heart and functioning to remove carbon dioxide from the blood and provide it with oxygen.
What are the Lungs?
The common respiratory condition where the bronchioles become narrower due to inflammation and a buildup of mucus.
What is asthma?
The ________ is where air inhaled from the mouth and nose meet.
What is pharynx?
The nasal cavity does these three things for our respiratory system.
What is warms, filters, and moistens inhaled air?
The long, thin muscle that allows our lungs to enlarge and take in air when it contacts.

What are yawns?
The tiny hair like projections inside the respiratory system that help remove inhaled particles.
What are cilia?
The _______ lung is slightly smaller than the ________ lung.
What is left and right?
The fatty layer inside of alveoli that keep them from collapsing. Premature babies lack sufficient amounts of this, making them prone to respiratory illnesses.
What is surfactant?
The condition where air sacs in the lungs pop.
What is emphysema?
Involuntary spasms of the diaphragm will cause the human body to _________.
What is hiccup?
This substance helps keep the internal lining of your air passages moist. It also helps trap pathogens, pollens, and dust so that it can be coughed out.
What is mucus?
The process of taking in oxygen from the outside world, providing it to the blood, and expelling carbon dioxide.
What is internal respiration?
The organ that is responsible for producing tears to moisturize our eyes and nostrils.
What is the lacrimal gland?
The condition where infection leads to the alveoli filling with fluid and/or pus.
What is pneumonia?
The process where oxygen and carbon dioxide are swapped in the capillaries that surround the alveoli.
What is diffusion?
The respiratory system's first line of defense against pathogens. Propels unwanted particles and contaminants upwards out of the respiratory system.

What is the mucociliary escalator?
