Air moves through the respiratory system in a continuous cycle. which of the following correctly describes the movement of air through the parts of the respiratory system?
a) nose, trachea, bronchioles, alveoli, cells
b) nose, pharynx, alveoli, bronchioles, capillaries
c) trachea, bronchi, pharynx, capillaries, cells
d) trachea, bronchioles, bronchi, alveoli, pharynx

Option A

Explanation:

The respiratory system consists of a continuous cycle which describes the movement of the air from the nose to the cells of the body.

The air enters the body through nose and travels to the lungs via trachea. In lungs the air reaches the bronchioles which has aveoli ( sac like structure for the exchange of gases).

From here the air( oxygen) is transferred to the different cells of the body.
