Question

Explain the path taken by the inhaled air from the nostrils to the lungs ?

Answer 1

Breathing starts at the nose and mouth. You inhale air into your nose or mouth, and it travels down the back of your throat and into your windpipe, or trachea. Your trachea then divides into air passages called bronchial tubes. ... Here, oxygen from the inhaled air passes through the alveoli walls and into the blood.

Answer 2

First -we take o2 inside in our body from our nose or mouth.
second - the air then goes to the wind pipe where treachea is which are supported by cartilage rings to help it to carry the air to the lungs.
third- the air reaches lungs and the alveoli ( last part of lungs ) where the blood capillaries exchange the gases and then the co2 is exhaled out.
