Short answer

The structure that matches the description of being a chamber behind the oral cavity and between the nasal cavity and larynx is the pharynx (a).

Step-by-step solution

a. Pharynx

The pharynx is a muscular tube that connects the nasal and oral cavities to the larynx and esophagus. It is located behind the oral cavity and between the nasal cavity and larynx. Therefore, it matches the given description.

b. Glottis

The glottis is the opening between the vocal cords in the larynx. It does not match the description of being a chamber behind the oral cavity and between the nasal cavity and larynx.

c. Larynx

The larynx, also known as the voice box, is found below the pharynx and contains the vocal cords. It is not a chamber behind the oral cavity and between the nasal cavity and larynx, so it doesn't match the description.

d. Trachea

The trachea, or windpipe, is a tube that connects the larynx to the bronchi. It is not the chamber behind the oral cavity and between the nasal cavity and larynx described in the exercise.

e. Bronchi

The bronchi are the main passageways from the trachea to the two lungs. They also do not fit the description of being a chamber behind the oral cavity and between the nasal cavity and larynx.

f. Bronchioles

The bronchioles are smaller tubes branching from the bronchi within the lungs. They also do not fit the description. Based on our analysis,

Answer:

The structure that matches the description of being a chamber behind the oral cavity and between the nasal cavity and larynx is the pharynx (a).
