Respiratory System Anatomy 2

Front

What is the trachea?

Back

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

Front

What is the diaphragm?

Back

The diaphragm is a dome-shaped muscle located at the base of the thoracic cavity that plays a crucial role in breathing by contracting and relaxing to change the volume of the thoracic cavity.

Front

What are bronchi?

Back

The bronchi are the two main branches that split from the trachea, leading to each lung and further dividing into smaller bronchioles.

Front

What is the function of the sinus cavities?

Back

The sinus cavities lighten the skull, act as resonance chambers for speech, and produce mucus, but they do not purify air.

Front

What is the nasopharynx?

Back

The nasopharynx is the upper part of the pharynx located behind the nose, and it is the most superior part of the pharynx.

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 the role of the larynx?

Back

The larynx, or voice box, is responsible for producing sound and protecting the trachea against food aspiration.

Front

What is the function of the bronchioles?

Back

Bronchioles are small air passages that branch from the bronchi and lead to the alveoli, regulating airflow and facilitating gas exchange.

Front

What is the purpose of mucus in the respiratory system?

Back

Mucus traps dust, pathogens, and other particles, helping to keep the airways clear and moist.

Front

What is the role of cilia in the respiratory system?

Back

Cilia are tiny hair-like structures that line the respiratory tract, helping to move mucus and trapped particles out of the airways.
