12BIO Intro Gas Exchange

The trachea leads to the...

• Bronchioles
• Bronchi
• Esophagus
• Pulmonary Vessel

The air sacs that are covered with capillaries where gas exchange takes place.

• Bronchi

• Trachea

• Oxygen

• Alveoli

What are the products of cellular respiration?

• ATP, water, carbon dioxide and heat

• Water and oxygen

• Oxygen and carbon dioxide

• Water, ATP and carbon dioxide

When air pressure inside the lungs is less than air pressure in the atmosphere...

• Air moves into the lungs
• Air moves out of the lungs

What are the main muscles of inhalation?

• The diaphragm and intercostal muscles

• The scalenes and the abdominal muscles

• The diaphram and abdominal muscles

• The diaphragm and latissimus muscles

A contraction of the diaphragm during inhalation causes it to flatten. What else does the contraction result in?

• An increase in the volume of the chest cavity

• Increase in alveolar pressure

• A decrease in lung volume

• A decrease in the volume of the thoracic cavity

What pressure gradient is exhalation triggered by?

• The pressure in the lungs is less than the pressure of the atmosphere

• The pressure in the lungs is greater than the pressure of the atmosphere

What is the function of the bronchi?

• Transport air from nose to lungs
• Transport air from trachea to lungs
• Transport air from lungs to alveoli
• Transport air from alveoli to blood

Within the lungs, the exchange of oxygen and carbon dioxide occurs between the ___ and the capillaries. 

• trachea 
• bronchi 
• alveoli
• diaphragm
