Study Notes
Respiratory System Structure and Function
- The warming and humidification of inspired air primarily occurs in the nasal cavity.
- The larynx (voice box) houses the vocal cords and is involved in sound production.
- The trachea (windpipe) leads to the bronchi in the respiratory system.
- The trachea and bronchi have a cylindrical shape due to the presence of C-shaped cartilage rings, providing support.
- An estimated 300 million alveoli are present in an adult's lungs.
- The nasal cavity is responsible for the warming and humidification of inspired air.
- The main function of the larynx is sound production.
- The trachea and bronchi contain cartilage to support their structure.
- Gas exchange with the blood primarily occurs in the alveoli of the lungs.
