of the______​

Answer 1

Answer:

The Pharynx Connects the Nasal and Oral Cavities to the Larynx and Esophagus. The pharynx, or throat, is shaped like a funnel. During respiration, it conducts air between the larynx and trachea (or “windpipe”) and the nasal and the oral cavities.

Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them.
