Term
What parts make the conducting zone?
Definition
nose, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles
Term
What parts make the respiratory zone?
Definition
respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
Term
Pulmonary ventilation
Definition
inhale and exhale (respiratory system)
Term
External respiration
Definition
from lungs to blood (interaction of respiratory and circulatory ystems)
Term
Internal respiration
Definition
from blood to cells (circulatory systems)
Term
What does the conducting airways do to air?
Definition
Filter, warm, and moisten air
Term
Which conducting structure has the lowest cross sectional area?
Definition
Trachea
Term
Which structure in the conducting system has the largest cross sectional area?
Definition
Bronchioles (terminal)
Term
Which part of the respiratory system has the greatest cross sectional area?
Definition
Alveoli
Term
Which part of conducting system do you find cartilage?
Definition
The trachea and some in the bronchi
Term
Where is cilia found in the conducting zone?
Definition
Trachea, Bronchi, Bronchioles
Term
Is cilia in the respiratory zone?
Definition
Yes, some on the respiratory bronchioles, which is a transition zone
Term
What single structure in both the conducting zone and respiratory zone does not have any smooth muscle?
Definition
Alveolar sacs
Term
What types of innervation do conducting airway smooth mm have?
Definition
sympathetic and parasympathetic
Term
What type of receptors work in the sympathetic divison for the lungs?
Definition
Adrenergic, specifically B2 receptors that leads to relaxation and dilation of airway
Term
What type of receptors are found in the parasympathetic system?
Definition
uses ACh on muscarinic receptors that leads to contraction and constriction of airways
Term
What chemicals will activate the sympathetic system?
Definition
Epinephrine from adrenal medulla and B2 agonists like isoproterenol
