Answer 2

Concept

The circulation receives oxygen from the lungs during gas exchange. The blood and lungs exchange carbon dioxide at the same time. This occurs in the lungs between the capillaries, which are a network of microscopic blood arteries found in the walls of the alveoli, and the alveoli themselves.

Given

A diagram showing exchange of gases.

Find

In which organ the process is taking place.

Solution

We can breathe thanks to our respiratory system and lungs. They expel carbon dioxide and inspire oxygen into our bodies, a process known as inspiration or inhalation (called expiration, or exhalation). The process of breathing involves the exchange of oxygen and carbon dioxide.

Exchange of gases takes place in the wall of alveoli of lungs where blood gives away Carbon dioxide and takes oxygen.

Hence, the diagram is showing B) the lungs.
