Final answer:
The correct pattern of airflow during inhalation is air enters the nose or mouth, travels up the trachea, and exits through the nose or mouth.
Step-by-step explanation:
The correct pattern of airflow during inhalation is Option 4: Air enters the nose or mouth, travels up the trachea, and exits through the nose or mouth.
During inhalation, air enters the body through the nasal cavity or mouth. It then travels down the trachea, a long tube that leads to the lungs. Finally, the air exits through the nose or mouth.
The bronchi, bronchioles, and alveoli are structures within the lungs where gas exchange occurs during inhalation.
