Comprehensive I Human Case Study: Week #4 A 5 Year
Old Patient Reason For Encounter Cough And Trouble
Breathing Class 6541 Walden University Latest Case
Study
, What are the four major sites responsible for adjusting alveolar ventilation
rate?
-respiratory control centres (source of central pattern generator)
-central chemoreceptors
-peripheral chemoreceptors
-pulmonary mechanoreceptors (in the muscle, respond to things like stretch)
How do chemoreceptors control breathing?
Chemoreceptors detect changes in PO2 and PCO2 levels, they send this
information to the respiratory control centre which would ultimately control
breathing
What are the major muscles involved in inspiration?
-diaphragm and external intercostal muscles
What are the muscles used in expiration?
-internal intercostal muscles
-abdominal muscles are used in forced expiration
Why do the larynx and pharynx open during inspiration?
-to create a bigger area so more air can be breathed in
