Pulmonary Artery Anatomy

Pulmonary Artery Anatomy The final of the upper respiratory tract finishes with the larynx (voice box). The larynx is mainly constructed from cartilage, dividing in to 4 main structures: a thyroid problem cartilage, the cricoid collagenous cartilage, the arytenoid cartilage, as well as the epiglottis. The thyroid, cricoid in addition to arytenoid are made up from hyaline cartilage, and the epiglottis is comprised from elastic fibrocartilage. Hidden inside the arytenoid cartilage would be the vocal cords and entry to the trachea.

The respiratory system functions of the larynx should be protect the lower respiratory tract (through the epiglottis blocking typically the passage of food to the trachea whilst eating as well as swallowing), to humidify and also warm the air (through often the moist mucosa and vascularity of the walls), and to generate speech and sound (through the use of the vocal cords).
