RESPIRATORY I
What is Boyle's Law
Two main muscles of inspiration
What are the diaphragm and external intercostals
This lung has a cardiac notch
What is the left lung
The physical movement of air into and out of lungs is called
What is Ventilation (Pulmonary)
Innervation of the Diaphragm
What is Phrenic N.
The physical movement of air in/out of lungs (inspiration/expiration)
What is (Pulmonary) Ventilation
Parasympathetic stimulation leads to ________ of the bronchiole
What is constriction
The pleural membrane adhered to the inner thoracic wall is known as the:
What is the Visceral pleura
Area posterior to nasal cavity, oral cavity and larynx
What is the Pharynx
The nasal cavity, pharynx and larynx are part of the upper or lower respiratory system?
What is Upper Respiratory System
The volume of air exchanged with normal, quiet breathing
What is Tidal Volume
The process of air that occurs when inspiratory muscles relax, lungs recoil, and thoracic volume decreases (therefore, alveolar pressure increases) is known as
What is Exhalation
The initial (or main) branches after trachea bifurcates at about the superior border of the 5th thoracic vert; each serves one lung
What are primary bronchi
Bronchodilation is the result of which kind of fiber stimulus
Protects food and water from entering the trachea
What is Epiglottis
Structures of the upper respiratory system
What is nasal cavity, pharynx, larynx
The structures of the Respiratory zone are:
What is respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
This structure is covered with free nerve endings to activate cough reflex when necessary to help prevent choking
What is Carina
A choking victim most likely has an object lodged in which zone?
What is conducting zone
Carbon dioxide is transported through the blood primarily as
What is bicarbonate
Pulmonary gas exchange occurs between which two structures?
What is alveoli and pulmonary capillaries
When an infant's surface tension is extremely high, this is usually due to (sufficient/insufficient) amounts of surfactant.
What is insufficient
Exposing the pleural cavity to the atmosphere will result in:
uncoupling of the lung from the chest wall (lung collapse, at least partial)
If a person were skiing up in the mountains, where atmospheric pressure is lower, they may feel they are having difficulty breathing because:
The lower atmospheric pressure lowers the PO2 and the diffusion gradient between the blood and the atmosphere is less. She would feel like she is having trouble breathing due to less oxygen getting into her blood.
What is higher PO2
