Anatomical Structures
The bronchial tree begins with this airway
What is the trachea?
Cannot be measured directly because it represents the air that will always stay in the lungs even after blowing out as hard as possible
What is Residual Volume (RV)?
It is the balance point where the lung and the chest force match
What is Resting level?
Of the major respiratory pressures, this pressure inside the lungs is considered the most important for understanding speech production.
What is alveolar pressure?
This dome-shaped muscle plays a crucial role in inspiration.
What is the diaphragm?
The maximum amount of air that can be exhaled following a maximum inhalation.
What is Tidal volume?
This common form of breathing is also referred to as automatic, metabolic, or involuntary breathing.
What is tidal breathing?
Turn airflow into sound.
What is phonation
These structures found are found in the lungs and are where oxygen and carbon dioxide exchange occurs.
What are the alveoli?
When combined, these volumes make up the air left in the lungs after a normal exhale
What are Expiratory Reserve Volume (ERV) and Residual Volume (RV)?
This pressure is found inside the thorax but outside the lungs, between the visceral and parietal pleural membranes.
What is pleural pressure?
Help shape speech sounds into recognizable phonemes.
What is articulation?
These are the two main parts that make up the respiratory system.
What are the Pulmonary apparatus and chest wall?
A numerical shift that happens to the resting lung volume when lying flat on your back
What is Resting lung volume level drops from 40% VC to 20% VC.?
During a quiet inhalation, the alveolar pressure undergoes this specific change
What is It becomes negative
Helps plan and coordinate by the brain. It also controls stress, rate and rhythm of speech.
What is the nerve system?
This structure is composed of the Rib cage wall, diaphragm, abdominal wall, and abdominal contents.
What is the chest wall?
The percentage of vital capacity of life breathing in a normal adult just breathing quietly.
What is 40% inhalation and 60% exhalation?
The muscles used to help in expiration by pulling the ribcage down.
What are the Internal intercostals?
This speech production is where sound produced by the vocal cord is amplified.
What is resonation?
