5 0

A: The pathway of air goes from the nasal cavity (or oral cavity) to the pharynx to the trachea to the primary bronchi (right and left) to the secondary bronchi to the tertiary bronchi to bronchioles to the alveoli (site of gas exchange)

B: when relaxed, the diaphragm is a dome shape. when we inhale, the diaphragm flattens down, increasing the thorax volume. this reduces the pressure in the thorax, so air moves into the lungs to equalize the pressure. when we exhale the diaphragm moves back into its relaxed dome position.

According to the given scenario, a coach benched a player after he took a big hit and the response of the crowd was to boo his decision and some of the players are upset. However,

<u>The coach took the correct precautionary measures</u>

<u />

According to the given scenario, we can see that a coach is worried about the impact of a big hit on one of his players and decided not to risk it by leaving him on the pitch.

As a result, benching the player after he has taken a "big hit" is a good call on the part of the coach because it is a necessary precaution even if the player is not showing any signs of concussion.

This is vital because the health and well being of the player is of paramount importance because until a test has been taken, one cannot ascertain the full extent of the damage done.
