Ventilation/Gas Exchange Practice Quiz

The Alveolar cells that secrete surfactant inside the alveolus are called: 

• Capillaries

• SA Node

• Type II Pneumocytes

• Type I Pneumocytes

The act of filling up your lungs with air and then breathing it out is called: 

• Circulation

• Ventilation

• Gas Exchanged

• Cellular Respiration

Every alveolus has a surrounding _ close by for efficient diffusion. 

What adaptation of the lungs provides a large surface area for respiratory gases to diffuse in and out: 

. .

• Alveoli

• Capillariesc

• Bronchioled

• Bronchi

The movement (dffusion) of gases is known as: 

• Ventilation

• Circulation

• Gas Exchange

• Cellular Respiration

This process requires oxygen and breaks down a glucose molecule to realease energy in the form of ATP. 

• Gas Exchange

• Cellular Respiration

• Circulation

• Ventilationd

Which of the following is NOT a consequence of emphysema? 

• Low carbon dioxide levels in the blood

• Low oxygen levels in the blood

• More rapid/labored breathing

• One large air space instead of multiple, reducing surface area

Which muscles contract during inspiration? 

• external intercostal muscles and diaphragm

• internal and external intercostal muscles

• Internal intercostal muscles and diaphragm
