NEET PG DENTAL EXAM

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: -The nose and trachea Breathing in through the nose warms and humidifies the air that is breathed in. Nose hairs help to trap any particles of dust. The warmed air enters the lungs through the windpipe, or trachea. The trachea is a hollow tube bolstered by rings of cartilage to prevent it from collapsing.

Detailed explanation-4: -The inside of your nose is lined with a moist, thin layer of tissue called a mucous membrane (say: MYOO-kus MEM-brayne). This membrane warms up the air and moistens it. The mucous membrane makes mucus, that sticky stuff in your nose you might call snot.
