Answer 2

A true statement about the entry of air into the lungs is - a) Air enters the body and travels to the lungs through the mouth and the nose

• The respiratory system is involved with the intake and exhales of gases. Also, it is responsible for the exchange of gases between the blood and the air.
• The route of air to the lungs is nose/mouth to the pharynx, then to the larynx and reaches the trachea.
• Now it either goes into the right or left lung where further it moves into bronchioles and alveoli where gas exchange between blood and air takes place.
