1. Describe the function of the nasal and oral pharynx for breathing.
The ph arynx is a muscular funnel that extends from the back of the nose to the larynx, or voice box. The nasal pharynx’s function is to allow air passage through it. The oral pharynx has both respiratory and digestive functions since it serves as a passageway for air, food, and water.
2. Describe the structure and function of the epiglottis.
The epiglottis is one of the nine cartilagous structures that make up the larynx. The function of the epiglottis is to prevent food and drink from falling down the airway, which is the trachea.
3. Describe the structure and location of the trachea. Explain its function in relation to respiration.
The trachea is lined by cartilage and divided into two branches, called the bronchi, which enter the left and right lungs. It is composed with pseudostratified columnar epithelium. The trachea is the windpipe which conditions – warms, moistens, and removes particles – of the air inhaled.
4. Describe the structure and function of the cricoid cartilage.
The cricoid cartilage is the only complete cartilage of the larynx. Its function is to join various muscles, ligaments, and cartilages that are involved in closing and opening the airways such as the epiglottis. A cartilage is softer than a bone, so it is fully or partially flexible. It is also involved in the production of speech.
5. Explain the function of the larynx.
The Larynx acts as an airway to the lungs and provides us a way to communicate – voice.
6. List and describe the two major branches of the airway to the lungs.
The two major branches of the airway to the lungs are the bronchi. The right branchus is wider and shorter than the left, which makes is more vulnerable to foreign invasion. The first few levels of branchi are supported by rings of cartilage. Branches after that have irregularly shaped discs of cartilage, while the latest levels have
