Irvin Ramirez 09 Respiratory Concept
Upper respiratory structures and functions
Larynx
Pharynx
mouth
Nose
Layers of the pleurae
Inner layer:: visceral plerua
Attachtes to wall
Outerlayer: Partiel pleura
Lower respiratory structures and functions
Bronchi
Bronchioles
Trachea
Helps lungs
Alveoil
Major functions of the respiratory system:
Trachea
Larynx
Lungs
NAsal Cavity
Pharynx
Bronchii
Bronchioles
Compare and contrast the mechanism of inspiration and expiration
Expiration
Diasphgram & intercostalmuscles contract
Allows air to enter lungs
Inspiration
Involves gasses leaving the lungs
Then muscles relax forcing air to flow out
Volume and Pressure relationships in thoracic cavity
Prssure
increase volume and cuases decrease in the intrathoraci pressure
Volume
Expands
diaphgram contrcts
intercostal muscles conact
Expanding thoraci cvity
Respiratory volumes and capacities
Capcities
derived from a summation of different lung volumes
Volumes
refers to volume gas in lungs given during respiratory cycle
Internal vs. external respiration
External
in lungs or gills
realsese carbon dioxide
when body rakes oxygen from atomsphere
Internal
In body tissues
take oxygen in from blood
realease carbon dioxide
Disorders of the respiratory system
cystic fibrosis
lung cancer
asthma
bronchitis
pneumia
