Entry point for air.
What are nostrils/nasal cavity?
The process of breathing.
What is ventilation?
Oxygen moves based on this gradient.
What is pressure gradient?
Number of lobes in right lung.
What is 3?
Air flows into lungs when pressure is this relative to outside.
What is lower?
This structure prevents food from entering airway.
What is the epiglottis?
Movement of gases in lungs.
What is pulmonary gas exchange?
Most oxygen is transported in blood bound to this.
What is hemoglobin?
Number of lobes in left lung.
What is 2?
Air flows out when pressure is this.
What is higher?
This tube contains C-shaped cartilage rings.
What is the trachea?
Gas exchange in tissues.
What is systemic gas exchange?
Most CO₂ is transported as this.
What is bicarbonate?
This indentation is found in the left lung.
What is the cardiac notch?
This muscle contracts during inhalation.
What is the diaphragm?
These structures lead directly to alveoli.
What are bronchioles?
The respiratory system helps regulate this.
What is pH?
Gas movement from high to low pressure follows this law.
What is Dalton’s Law?
This is the entry point of lung structures.
What is the hilum?
Air not used for gas exchange.
What is anatomical dead space?
This is where gas exchange occurs.
What are alveoli?
This nerve controls diaphragm movement.
What is the phrenic nerve?
More volume = Lower pressure
OR
More pressure = less volume
What is Boyle's Law?
This membrane allows rapid gas exchange.
What is the respiratory membrane?
Forced exhalation uses these muscles.
What are internal intercostals and abdominal muscles?
