Respiratory System Flashcards
What are the functions of the respiratory system
Gas exchange
Speech
Immune protection
Ph homeostasis
Olfacation
Provides passage way for air to reach respiratory zone
Conducting zone
Major entrance and exit of air for respiratory system
Nose
Space in skull that communicates with external nose
Nasal cavity
It is the anatomical term for the throat
Pharynx
Entrance to lower respiratory tract and also known as the voice box
Larynx
Vibrate to produce sounds
Vocal folds
Extends from larynx to mediastinum
Windpipe
Trachea
Collective name for airways in the lungs
Bronchial tree
Bronchi eventually branch into __________
Bronchioles
Consists of respiratory bronchioles, alveolar ducts, alveolar sacs made of individual alveoli
Respiratory zone
Thin walls that allow gas exchange
Alveoli
How many lobes does the right side of the lungs have
3
How many lobes does the right side of the lungs have
2
Is an anatomical structure where pulmonary arteries, pulmonary veins,nerves, lymphatic and primary bronchi enter or leave each lungs
Hilum
Pressure within alveoli
Intrerpulmonary pressure
Pressure within pleural cavity
Intrapulmonary pressure
Pressure within pleural cavity
Intrapleural pressure
It is the difference between intrapleural and intrapulmonary pressure Wich determines the size of the lungs
Transpulmonary pressure
What is the constant atmospheric pressure of the lungs at sea level
760 mm hg
Occurs when atmospheric pressure is greater than intrapulmonary pressure
Inhalation
Occurs when intrapulmonary pressure is greater than atmospheric pressure
Exhalation
For gasses pressure is cause by collisions within the wall of a container
Boyle’s law
Pressure is _________ related to volume
Inversely
