Front

What is the function of the epiglottis?

Back

The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food and liquid from entering the airway.

Front

What are the conchae and their role in the respiratory system?

Back

The conchae are bony structures in the nasal cavity that help to warm, humidify, and filter the air we breathe.

Front

What is the thoracic cavity and its significance in respiration?

Back

The thoracic cavity houses the lungs and heart, playing a crucial role in the mechanics of breathing.

Front

What is the diaphragm and how does it function in respiration?

Back

The diaphragm is a dome-shaped muscle that contracts and flattens to create a vacuum that pulls air into the lungs.

Front

What are bronchi and their role in the respiratory system?

Back

Bronchi are the main passageways that branch from the trachea into the lungs, allowing air to enter and exit.

Front

What are bronchioles and how do they differ from bronchi?

Back

Bronchioles are smaller branches of the bronchi that lead to the alveoli, where gas exchange occurs.

Front

What are alveoli and their function in the respiratory system?

Back

Alveoli are tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged between the air and blood.

Front

What is the role of the trachea in the respiratory system?

Back

The trachea, or windpipe, is a tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Front

What is the pharynx and its function in the respiratory system?

Back

The pharynx is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus, playing a role in both breathing and swallowing.

Front

What is the difference between the abdominal cavity and the thoracic cavity?

Back

The abdominal cavity contains digestive organs, while the thoracic cavity contains the lungs and heart.
