Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
Answer:
The pharynx, or what we know as the "throat," is a dual duty body part. It has the job of both swallowing/ moving food to the esophagus. It is also the channel that allows air from your nasal/ oral cavities to flow down to your larynx, or voice box.
Hope this helps!
