They both help the organism to have gaseous exchange with its surrounding
Using many structures called gill lamellaes
gaseous exchange
Fish have gills to breathe in the water. they swim in the water and are adapted :D :D :D
Plants and animals have adapted to feed, reproduction, and life on land by utilizing oxygen or carbon dioxide that is absorbed through lungs or via photosynthesis rather than using gills. They have adapted with fur to keep them warm and legs to move them safely on land. Plants have adapted to utilize sunlight and animals to reproduce.
A gill is a filamentous organ specialized for the exchange of gases underwater. Some aquatic animals have gills that are adapted in such a way so as to allow them to breathe out of the water.

Gaseous exchange is a natural process, ventilation is a forced process.
To exchange for oxygen in water.
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
Most reptiles exchange gases through their lungs. The lungs of reptiles are folded so as to make enough room for gaseous exchange.
