Larynx: pharynx and larynx function with tabular form
The larynx is a muscular organ that forms an air passage for the lungs and vocal cords.
The pharynx and larynx are the structures present in the neck region of vertebrates.
The pharynx is a fibromuscular tube that extends from the base of the skull to the esophagus.
On the other hand, the larynx is an apparatus formed by cartilage, muscles, mucous membranes and ligaments that protects the entrance to the lower respiratory tract such as the bronchi, the trachea and the lungs. The larynx also houses the vocal cords.
The pharynx and larynx differ in their structure and function. Below, in a tabular column, are the differences between pharynx and larynx.

| It is part of the respiratory and digestive system. | It is part of the respiratory system. |
| The walls of the pharynx are made up of muscles. | The walls of the larynx are made of cartilage. |
| It is made up of three regions, namely the oropharynx, nasopharynx, and laryngopharynx. | It is made of four cartilages, namely, cricoid cartilage, thyroid cartilage, corniculate cartilage, and arytenoid cartilage. |
Both the oral and nasal cavity open into the pharynx. The pharynx, in turn, opens into the esophagus and larynx. The larynx opens into the trachea. Both food and air pass through the pharynx.
