Diaphragm: The diaphragm is a dome-shaped muscle that separates the chest from the abdomen and plays a crucial role in breathing.

Front

What is the flap of skin that covers the opening to the windpipe during swallowing?

Back

Epiglottis: The epiglottis is a flap that prevents food and liquid from entering the trachea during swallowing.

Front

What are the two main branches from the trachea that lead to each lung?

Back

Bronchi: The bronchi are the two main passageways that branch off from the trachea and lead into the lungs.

Front

Where does the exchange of oxygen and carbon dioxide occur in the lungs?

Back

Alveoli: Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

Front

What is the primary function of the respiratory system?

Back

The primary function of the respiratory system is to facilitate the exchange of oxygen and carbon dioxide between the body and the environment.

Front

What is the role of the nasal cavity in the respiratory system?

Back

Nasal Cavity: The nasal cavity filters, warms, and moistens the air we breathe before it enters the lungs.

Front

What is the function of the bronchioles?

Back

Bronchioles: Bronchioles are small air passages that branch off from the bronchi and lead to the alveoli, allowing air to reach the alveoli.

Front

What is the purpose of the cilia in the respiratory system?

Back

Cilia: Cilia are tiny hair-like structures that line the respiratory tract and help to trap and move particles out of the airways.

Front
