Adam's Apple
The first structure in the lungs that oxygen passes through.
Primary Bronchi
What is the term for breathing in and out? (Not the term for normal breathing)
Ventilation
Gas exchange occurs in what structures?
Alveoli
The disease where a person stops breathing for short periods of time during sleep
These vibrate with exhaled air
Another name for the windpipe?
Trachea
If the diaphragm is contracting and moving downward, the direction of airflow is: (in or out)
Into the lungs
What is the structure that leads to the small balloon-like structures where gas exchange occurs?
Bronchioles
The respiratory rate of a newborn is:
40 breaths per minute
Air enters the nasal cavity of the respiratory system through the:
External nares
The term for the muscles that are inferior to the lungs and cause changes in pleural pressure.
Diaphragm
If the diaphragm is relaxed and moved superiorly, the size of the lungs: (Increases or decreases)
Decreases
What lipid-based substance is used to keep the area where gas exchange occurs moist?
Surfactant
A deep breath is taken, the glottis is closed, and air is forced out of the lungs against the glottis; this process clears the upper respiratory passageways.
Sneezing
The cartilage that is beneath the Thyroid cartilage is the:

Hemoglobin
Which structure responds to decreased oxygen levels in the blood?
Chemoreceptors
The bone that is more superficial than the epiglottis and located in the same area is the:
Hyoid bone
In healthy lungs, this pressure is always lower than atmospheric pressure.
Intrapleural Pressure
What are the two muscles that cause abdominal pressure to rise?
Transverse Abdominis
External/Internal Obliques
When oxygen reaches the structures that it is needed at, an exchange occurs where oxygen is deposited and carbon dioxide is picked up. What structure does this happen in?
Capillaries
Which structure smooths out the basic rhythm of breathing set by the medulla?
Pons Center
