Before we start learning about the Pharynx and larynx, it is essential to learn what the Pharynx and Larynx. These are the two organs situated in the area around the neck region of a human body. The Pharynx is a part of the alimentary canal, while the Larynx is a portion of the trachea.
The Pharynx is located posterior to the oral and nasal cavities, forming part of the digestive and respiratory systems. It acts as a common channel for swallowing and respiration. The Pharynx is divided into three regions – The nasopharynx, Oropharynx, and Laryngopharynx.
Whereas, the Larynx connects the lower part of the Pharynx with the trachea. It not only acts as a valve to the passage of air but also helps in the process of vocalization and swallowing. The Larynx is divided into three parts – supraglottis, glottis, and subglottis.
Differences between the Pharynx and Larynx
There are several similarities between the Pharynx and the Larynx, yet there are many ways in which these two organs are different from each other. These organs are very essential for the proper functioning of the human respiratory and the digestive system. The table of differences between the Pharynx and Larynx which has been prepared by experts of is
