Explanation: 

Detailed explanation-1: -What Are the Parts of the Respiratory System? The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth. If it goes in the nostrils (also called nares), the air is warmed and humidified.

Detailed explanation-2: -Because the pathway of air entering the body from the mouth is shorter than the pathway for air entering from the nose, the mouth does not warm and moisturize the air entering the lungs as well as the nose performs this function.

Detailed explanation-3: -(i) during inhalation, ribs move inward and diaphragm is raised. (ii) the gaseous exchange takes place in the alveoli. (iii) haemoglobin has greater affinity for carbon dioxide than oxygen. (iv) alveoli increase surface area for the exchange of gases.
