Anatomical Structures of Respiration
When contracted, this organ flattens and moves downward, thus increasing the vertical dimension of the thoracic cavity.
What is the diaphragm?
The volume of air inhaled or exhaled during one cycle of respiration.
What is tidal volume?
The process of moving air into and out of the lungs which are controlled by muscle movements such as the diaphragm.
What is breathing?
40% inhalation
60% exhalation
What is the percentage for the cycle of life breathing?
10% inhalation
90% exhalation
What is the percentage of airflow for speech production?
These muscles elevate the rib cage during inhalation, thus increasing the volume of the thoracic cavity.
What are the external intercostal muscles?
The maximum volume of air that can be inhaled above the tidal volume.
What is inspiratory reserve volume?
The gas exchange in the lungs alveoli and bloodstream.
What is external respiration?
Provides oxygen for cellular energy production and removes carbon dioxide waste.
What is the role of the gas exchange from the respiratory system?
Inhalation is shortened while exhalation is prolonged to control the outward flow of air that is needed for speech.
What occurs during speech breathing?
These tiny air sacs are at the end of the respiratory tract and are the site of gas exchange.
What are alveoli?
The volume of air remaining in the lungs at the end-expiratory level.
What is functional residual capacity?
Oxygen is transported through the bloodstream from lungs to tissue and carbon dioxide is carried from tissues back to lungs.
What is transport of gases?
Airflow from the respiratory system causes the vocal folds to vibrate.
What is the power source for speech production?
Air is inhaled through the mouth.
Where is airflow located during speech breathing?
This hollow tube consists of 16-20 rings of hyaline cartilage and its lumen is lined with pseudostratified ciliated columnar epithelium.
What is the trachea?
The maximum volume of air that can be exhaled after taking the deepest inhalation.
What is vital capacity?
The gas exchange between the bloodstream and the body's tissues.
What is internal respiration?
Airways are lined with mucus and tiny hair structures called cilia, that trap and remove dust, germs, and other irritants from the air one breathes.
What is the protection function of the respiratory system?
This is maintained by the ability to control breathing in a steady manner, along with voice quality.
What is pitch?
These muscles run downward and backward, and if they are weak, they can impair sustained phonation and vocal intensity.
What are the internal intercostal muscles?
The volume of air the lungs can hold after a maximum, long inhalation and is also the sum of all lung volumes.
What is total lung capacity?
The vibration of vocal folds are caused by airflow to produce this.
What is sound?
Airflow from the respiratory system moves past the olfactory nerves in the nasal cavity, allowing us to detect odors.
What is the connection between olfaction and the respiratory system?
The ability to control and produce adequate breaths, controlling the tongue, lips and jaw in an efficient manner to create clear sounds.
What is articulation?
