Front

What is the pharynx?

Back

The pharynx is the region of the digestive and respiratory systems that extends from behind the nasal cavities to the esophagus, commonly referred to as the throat.

Front

What are bronchioles?

Back

Bronchioles are small airways within the lungs that carry air to the alveoli and whose walls do not contain cartilage.

Front

What is emphysema?

Back

Emphysema is a chronic respiratory disorder that involves damage to the bronchioles and alveoli, leading to difficulty in breathing.

Front

What is the respiratory center?

Back

The respiratory center consists of groups of nerve cells in the medulla oblongata near the base of the brain that are responsible for the cyclic nature of respiration.

Front

What is the nasal cavity?

Back

The nasal cavity is an internal space directly behind the external nose, involved in the respiratory process.

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 alveoli?

Back

Alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

Front

What is tidal volume?

Back

Tidal volume is the amount of air that is inhaled or exhaled during normal breathing.

Front

What is partial pressure in the context of respiration?

Back

Partial pressure refers to the pressure exerted by a specific gas in a mixture of gases, important for understanding gas exchange in the lungs.

Front

What is the role of the larynx?

Back

The larynx, also known as the voice box, is involved in sound production and protects the trachea against food aspiration.
