Study Notes
Respiratory System Overview
- The respiratory system allows air to pass from the nose to the trachea through the pharynx and larynx
- The trachea is a long, straight tube, held open by C-shaped cartilage rings
- The trachea is lined with cilia and goblet cells that produce mucus; this traps foreign particles
- The nose contains a nasal cavity that leads to the pharynx
- The nasal cavity is lined with cilia, hairs, and goblet cells; these structures filter, warm, and moisten the air
- Air is cleaned of dust, pollen, and other foreign substances that become trapped in the mucus
