Q

Nose

A

~ We are supposed to inhale through our nose because the hairs and mucus trap dirt particles and bacteria in the nose.
~ Air is warmed and moistened by the blood vessels. Warm, moist air helps oxygen to pass from the lungs into the bloodstream more easily.

Q

Bronchus and Bronchioles

A

~We have two bronchi. Each bronchus carries air between the trachea and a lung. The two bronchi subdivide many times to form tiny tubes called bronchioles. Bronchioles carry air to and from the alveoli.
