External respiration takes place in the lungs

Explanation:

External respiration takes place in the lungs, in the exchange process of carbon dioxide (CO2) and Oxygen (O2). This means that in the lungs, oxygen diffuses into the blood and carbon dioxide diffuses into the alveoli (smallest functional structure of the lungs). In order to understand the difference, in the other hand we have internal respiration which occurs in metabolizing tissues, where the exchange of oxygen and carbon dioxide occurs in the cells.
