Nasopharynx Diagram Quiz

Nasopharynx and Related Structures

• The nasopharynx is the upper part of the pharynx located behind the nasal cavity.
• It serves as a pathway for air to move from the nasal cavity to the oropharynx.

Nasal Cavity

• The nasal cavity is the large air-filled space above and behind the nose.
• It is responsible for filtering, warming, and humidifying the air we breathe.

Oropharynx

• The oropharynx is the middle portion of the pharynx located behind the oral cavity.
• It plays a role in both the respiratory and digestive systems, as it serves as a passage for air and food.

Hypopharynx

• The hypopharynx is the lower part of the pharynx that connects to the esophagus and larynx.
• It is responsible for directing food and air into the correct passages during swallowing and breathing.

Esophagus

• The esophagus is a muscular tube that connects the pharynx to the stomach.
• It transports food and liquids from the mouth to the stomach via peristaltic movements.

Larynx

• The larynx, commonly known as the voice box, is located between the pharynx and trachea.
• It is essential for phonation (production of sound) and protects the airway during swallowing.

Trachea

• The trachea, also known as the windpipe, is a tube that connects the larynx to the bronchi of the lungs.
• It provides a clear airway for air to enter and exit the lungs and is reinforced with cartilage rings for support.
