Question

Alveoli are the air sacs present in the lungs.

• A. True
• B. False

Answer 1

The correct option is A True

$\bullet$ Air enters the lungs through the trachea where it further gets subdivided into smaller branches at the end of which there are small sacs of air called alveoli.
$\bullet$ The exchange of gases takes place at the alveoli. It is where the blood takes in the oxygen from inhaled air and gives out the carbon dioxide that is produced by the body.
