Respiration Process 101
These muscles are key during exhalation because they help push down on the ribs and decrease the thoracic cavity
What are the internal intercostal muscles?
The body parts included in the posterior division of the upper airway
What are the nasopharynx, the oropharynx, and the laryngopharynx?
This muscle is dome-shaped and separates the thoracic cavity with the abdominal cavities.
What is the diaphragm?
This type of volume is the amount of air inspired or expired during normal breathing.
What is Tidal volume?
The respiratory system does this at the same time as it controls speech production, including the coordination of intensity, stress, and segmentation.
During this part of respiration, intrapulomary pressure decreases and lung volume increases
What is inhalation?
These muscles are crucial for inhalation because they elevate the ribcage and help expand the thoracic cavity
What are the external intercostal muscles?
These muscles contract when undergoing forced inhalation.
What are the sternocleidomastoid, scalenes, pectoralis minor, and serratus anterior?
This type of volume is the maximum amount of air that can be inspired from the normal inspired tidal volume amount.
What is Inspiratory reserve volume (IRV)?
These utterances begin after taking the deepest inspiration possible and continuing until there is no more air supply.
What is extended steady utterances?
Without this kind of air, the structures located within the lungs would collapse
During gas exchange, oxygen leaves this body structure and enters the bloodstream to travel to tissues in the body
What are alveoli?
These muscles contract when undergoing forced exhalation.
What are internal intercostal, trans versus thoracis, and abdominal muscles?
This is the capacity as to which the volume of air in lungs reached the maximum inspiration.
What is Total Lung capacity (TLC)?
In this type of speech production, the relaxation pressure is almost always positive.
What are running speech activities?
These airways are responsible for exchanging oxygen and carbon dioxide during inhalation and exhalation
What are the terminal bronchioles?
These nerves are important for maintaining rib cage expansion and contraction
What are the intercostal nerves (T1-T11)?
This is a posterior muscle located on the neck and contracts during forced inhalation.
What are scalenes muscles?
This type of capacity is the volume of air that remains in the pulmonary apparatus after passive expiration.
What is Functional residual capacity (FRC)?
This type of pressure changes as stress is placed on certain sounds or syllables during speech production.
What is alveolar pressure?
This muscular action invoving the diaphragm needs to happen before the start of an extended utterance
What is inspiratory checking?
If this part of the sternum is punctured, the lungs could collapse
What is the xiphoid process?
These muscles are involved in abduction of the vocal folds and the vestibular folds.
What are the posterior cricoarytenoid and lateral cricoarytenoid?
This type of capacity is the sum of the inspiratory capacity, tidal volume, and the expiratory reserve volume.
What is vital capacity?
This is the percentages of inhalation and exhalation used in the breathing cycle during speech production.
What is 10% inhalation and 90% exhalation?
