100

Entry point for air.

What are nostrils/nasal cavity? 


100

The process of breathing.

What is ventilation? 


100

Oxygen moves based on this gradient.

What is pressure gradient? 


100

Number of lobes in right lung.

What is 3?

100

Air flows into lungs when pressure is this relative to outside.

What is lower?

200

This structure prevents food from entering airway.

What is the epiglottis?

200

Movement of gases in lungs.

What is pulmonary gas exchange? 


200

Most oxygen is transported in blood bound to this.

What is hemoglobin?

200

Number of lobes in left lung.

What is 2?

200

Air flows out when pressure is this.

What is higher?

300

This tube contains C-shaped cartilage rings.

What is the trachea?

300

Gas exchange in tissues.

What is systemic gas exchange? 


300

Most CO₂ is transported as this.

What is bicarbonate?  

300

This indentation is found in the left lung.

What is the cardiac notch?

300

This muscle contracts during inhalation.

What is the diaphragm?

400

These structures lead directly to alveoli.

What are bronchioles?

400

The respiratory system helps regulate this.

What is pH?

400

Gas movement from high to low pressure follows this law.

What is Dalton’s Law?

400

This is the entry point of lung structures.

What is the hilum?

400

Air not used for gas exchange.

What is anatomical dead space?


500

This is where gas exchange occurs.

What are alveoli?

500

This nerve controls diaphragm movement.

What is the phrenic nerve?

500

More volume = Lower pressure

OR

More pressure = less volume

What is Boyle's Law?

500

This membrane allows rapid gas exchange.

What is the respiratory membrane?

500

Forced exhalation uses these muscles.

What are internal intercostals and abdominal muscles?
