Study Notes
Functions of the Oropharynx
- Connects the mouth to the esophagus and serves as a passageway for both food and air.
- Plays a role in swallowing, allowing food to pass to the esophagus.
- Contains tonsils, which contribute to immune function.
Purpose of Chewing in Digestion
- Breaks down food into smaller particles, increasing surface area for digestive enzymes.
- Mixes food with saliva, which contains enzymes that initiate carbohydrate digestion.
- Facilitates the formation of a bolus, making swallowing easier.
Organ Not Part of the Gastrointestinal Tract
- The pancreas is often classified as an accessory organ due to its role in producing digestive enzymes, but it is not part of the GIT itself.
Function of the Laryngopharynx
- Acts as a junction where the respiratory and digestive tracts diverge.
- Directs food and liquids to the esophagus and air to the trachea during swallowing.
- Plays a role in protecting the airway during the swallowing process.
Primary Function of the Nasopharynx
- Serves as a passageway for air from the nasal cavity to the oropharynx and down to the lungs.
- Filters, warms, and humidifies the air entering the respiratory system.
- Houses the adenoids, which participate in immune response.
