TRUE OR FALSE<br> Oxygen is absorbed into the bloodstream in the trachea?
Arte-miy333 [17]

False. Oxygen is absorbed in the alveoli sacs of the lungs.

Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.
