Document Summary
Primary ciliary dyskinesia: cilium @ airway surface, doesn"t move cannot eliminate waste & mucus infections, dyskinesia: abnormality/impairment of movement. Hypoventilation, and autonomic dysregulation: brainstem doesn"t work well, gas exchange (o2 & co2, ph regulation, defense against airborne pathogens & foreign particles, vocalization. Interchanging of gases b/w body & environment: ventilation/breathing. Upper respiratory tract: muscles, can collapse: nasal cavity, tongue, pharynx, larynx, vocal cords. Lower respiratory tract: small, very strong, high pressure: trachea, bronchi, diaphragm, lungs. Innervated by- phrenic nerve: spinal segments c3, c4, c5. Muscles- passive at rest: used during voluntary expiration / increased respiratory needs. Internal intercostals: force ribs inward (forced exhalation) Definition: congenital malformation of diaphragm, most often containing an opening in the diaphragm, where abdominal organs herniate through diaphragm into chest cavity. Surgery: places abdominal organs in proper locations, close opening in the diaphragm. Enclosed by pleural sacs: double-wall membrane, middle filled w/ pleura.
