Respiratory Cycle
The movement of air into and out of the lungs.
Pulmonary Ventilation
This zone of the respiratory system warms, humidifies, and filters incoming air.
Conducting Zone
The ability to stretch
Compliance
Higher brain areas that control pulmonary ventilation.
Medulla / Pons
Law that describes the inverse relationship between pressure and volume of a gas
Boyd's Law
This part of the cycle refers to the movement of gases through the blood following gas laws.
Transportation of Gases
This alveolar cell type produces surfactant.
Alveolar Type II Cells
Ability to return to resting state after stretching
Elasticity
Mechanoreceptors that detect stretching from lung inflation
Stretch Receptors
Pressure of a gas surrounding an organism
Atmospheric Pressure
The process of gas exchange between the lungs and blood.
External Respiration
This zone of the respiratory system is the site of gas exchange
Respiratory Zone
Property describing the attraction of similar molecules to one another
Surface Tension
The protective reactions that occur when the lungs are exposed to irritants
Pulmonary Irritant Reflexes
Pressure of the pleural cavity
Intrapleural Pressure
The process of gas exchange between blood and the tissue.
Internal Respiration
This cell type is found in the alveoli but is part of the innate immune system.
Macrophage
Complex the prevents the surface tension from the moisture on the alveoli from overwhelming and collapsing the structure
Surfactant
Detect the changes in oxygen, carbon dioxide, and pH levels
Chemoreceptors
The pressure of air within the alveoli
Intra-alveolar Pressure
