Answer:

The respiratory system starts at the nose and mouth and continues through the airways and the lungs. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx.

Answer: nose and mouth

Explanation:

The first part is made up of the nose and mouth, through which air enters your body. The inside of your nose is called the nasal cavity. A mucous membrane lines your nasal cavity and it helps keep your nose moist. Little hairs inside your nasal cavity help filter the air you breathe in, and block dirt and dust from getting into your lungs.
