Anatomy of the upper respiratory system and upper digestive system.

Question 1

compartments of the head

Answer 1

1 cranial cavity (brain)
2 orbits (eyes)
2 auditory canals (ears)
2 nasal cavities (nose)
1 oral cavity (mouth)

Question 3

Q: What are the roles of the nasal and oral cavities, and how do they relate to the pharynx and larynx?

Answer 3

A:

The nasal cavities and oral cavity have structural features that contribute to smell and taste, modify air and food as they enter the body, and refine laryngeal sounds.
These cavities are entrances to the respiratory and digestive systems and lead into a common compartment called the pharynx.
The pharynx serves as a common passageway for air, food, and drink, guiding air towards the larynx (for respiration) and food towards the esophagus (for digestion).
