Study Notes
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.
