ANATOMY

Detailed explanation-1: -Air enters the respiratory system through the nose or the mouth, then travels down a pathway to the lungs. In the nostrils, air gets warmed and moistened. Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles.

Detailed explanation-2: -The THROAT collects incoming air from your nose and mouth then passes it down to the windpipe (trachea). The WINDPIPE (trachea) is the passage leading from your throat to your lungs. The windpipe divides into the two main BRONCHIAL TUBES, one for each lung, which divides again into each lobe of your lungs.

Detailed explanation-3: -Turbinates (conchae): There are three pairs of turbinates located along the sides of both nasal cavities. These folds inside your nose help warm and moisten air after you breathe it in and help with nasal drainage.

Detailed explanation-4: -The Paranasal Sinuses Surround the Nasal Cavities Mucosae line the paranasal sinuses and help to warm and humidify the air we inhale.

Detailed explanation-5: -The mucous membranes in your mouth and nose warm and moisten the air, and trap particles of foreign matter (like dirt and dust). The air passes through the throat into the trachea (windpipe).
