Respiratory System Anatomy
Number of lungs in the human body.
2
Air always flows toward this.
What is low pressure?
What is an inhalation?
A method that measures the volume of air moved during inspiration and expiration.
What is spirometry?
When someone exercises, this happens to their tidal volume.
What is increases?
Muscle immediately inferior to the lungs.
What is the diaphragm?
Before inhalation the pressure outside the body is ______ than inside the body
Higher
A "valley" on a spirometry reading represents this.
What is an exhalation?
Volume of air inhaled and exhaled during normal breathing.
What is tidal volume?
When someone exercises, this happens to their residual volume.
What is no change?
Also known as the voicebox.
What is the larynx?
During exhalation, the diaphragm and intercostal muscles do this.
What is relax or return to resting position?
A fancy term for breathing.
What is pulmonary ventilation?
Amount of air able to be inhaled after normal inhalation.
What is inspiratory reserve volume?
When someone exercises, this happens to their inspiratory reserve volume.
What is decreases?
Tiny clusters of air sac found at the end of each bronchiole.
What are alveoli?
This happens to pressure when the thoracic cavity decreases in size.
What is increase?
Vital capacity plus residual volume.
What is total lung capacity?
Amount of air able to be inhaled after normal exhalation.
What is expiratory reserve volume?
When someone exercises, this happens to their expiratory volume.
What is decreases?
These surround alveoli and facilitate diffusion of oxygen and carbon dioxide.
What are capillaries?
When the thoracic cavity increases in size, pressure decreases, and air moves this way.
What is into the body?
The amount of air that always remains in your lungs.
What is residual volume?
Total volume of air able to be forcefully inhaled and exhaled.
What is vital capacity?
When someone exercises, this happens to their total lung capacity?
What is slightly decreases?
