Front

What is the function of the trachea?

Back

The trachea serves as a passageway for air to travel to and from the lungs.

Front

What are alveoli?

Back

Alveoli are tiny air sacs in the lungs where gas exchange occurs, surrounded by capillaries.

Front

What does it mean when we say the walls of the alveoli and capillaries are permeable?

Back

It means that substances can pass through the walls of the alveoli and capillaries.

Front

What are bronchi?

Back

Bronchi are the branches of the trachea that lead into each lung.

Front

What is the epiglottis?

Back

The epiglottis is a flap of tissue that covers the opening to the windpipe during swallowing to prevent food from entering the airway.

Front

What is the primary function of the respiratory system?

Back

The primary function of the respiratory system is to facilitate gas exchange, bringing oxygen into the body and removing carbon dioxide.

Front

What role do capillaries play in the respiratory system?

Back

Capillaries surround the alveoli and allow for the exchange of oxygen and carbon dioxide between the blood and the air.

Front

What is the difference between the trachea and bronchi?

Back

The trachea is the main airway that leads to the lungs, while bronchi are the two main branches that split from the trachea into each lung.

Front

How does the diaphragm assist in breathing?

Back

The diaphragm contracts and flattens to create a vacuum that pulls air into the lungs during inhalation.

Front

What is the significance of gas exchange in the alveoli?

Back

Gas exchange in the alveoli is crucial for supplying oxygen to the blood and removing carbon dioxide from it.
