Hoit, J. D., Weismer, G., & Story, B. (2022).
What are the Muscles of Respiration?
Diaphragm: Large muscle that attaches to bottom six ribs on either side of the ribcage.
External intercostals: 11 pairs that run between ribs.Each pair originates on the lower surface of the rib, and the fibers course downward and forward at an oblique angle, inserting below, elevating portions of, or the entire, rib cage.
Internal intercostals: 11 pairs which are similar in structure to external intercostals. The intercostals lie deep to the external intercostals and run at an opposite angle (downward and backward) to that of the external intercostals.

What is the role of the diaphragm in speech production?
regulating airflow from the lungs.

What is the force that causes air to flow into the lungs during inspiration and out of the lungs during expiration?
Changes in the lung pressures.

Name 5 functions of the Respiratory System?
1.Inhalation and Exhalation Are Pulmonary Ventilation—That’s Breathing
2.External Respiration Exchanges Gases Between the Lungs and the Bloodstream
3.Internal Respiration Exchanges Gases Between the Bloodstream and Body Tissues
4.Air Vibrating the Vocal Cords Creates Sound
5.Olfaction, or Smelling, Is a Chemical Sensation
