Question

Diagram of respiratory surface is given below. Based on the diagram,
explain how are the efficiency of diffusion of gases increased in lungs?
​

Answer 1

Answer:

here's it

Explanation:

The structure of the lung maximizes its surface area to increase gas diffusion.

Having such a large surface area increases the amount of gas that can diffuse into and out of the lungs

Answer 2

How are lungs designed to increase efficiency of diffusion of gases?

• Inside the lungs the air passage divides into smaller and smaller tubes which finally terminate in small balloon like structure called alveoli.

• Lungs have a greater surface for exchange of gases because the total surface area of alveoli is 80 m² which is greater than the total surface area of entire body.

• In animals where the body size is large, respiratory pigments like haemoglobin take up oxygen from lungs and carry it to places that are deficient of oxygen.
