  2. Incomplete cartilaginous rings

  3. Bony rings

  4. Chitinous rings
Reveal answer Fill a bubble to check yourself
B Correct answer

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • The pharynx, or throat, is the passageway leading from the mouth and nose to the oesophagus and larynx. 
  • The pharynx permits the passage of swallowed solids and liquids into the oesophagus, and conducts air to and from the trachea, or windpipe, during respiration. 
  • The pharynx also connects on either side with the cavity of the middle ear by way of the Eustachian tube and provides for equalization of air pressure on the eardrum membrane, which separates the cavity of the middle ear from the external ear canal. Hence, The short tube leading from the nose is pharynx.
So, the correct answer is 'pharynx'
