Answer:
The Path of Air in Respiration
The path of air followed for respiration is:
Nostrils: Air enters the body through the nostrils.
Nasal Cavity: The air is warmed, moistened, and filtered as it passes through the nasal cavity.
Pharynx: The air then travels through the pharynx, a common passage for both air and food.
Larynx: Air moves into the larynx, or voice box.
Trachea: The air passes through the trachea, or windpipe.
Bronchi: The trachea divides into two bronchi, one leading to each lung.
Bronchioles: The bronchi branch into smaller tubes called bronchioles.
Alveoli: The bronchioles end in tiny air sacs called alveoli, where oxygen and carbon dioxide exchange takes place.
