Question

Gills are delicate structures. How do these remain protected from damage?

Answer 1

Gills:

• The gills are the organs present in the organisms living in the water to help in the respiration process.
• These organs absorb the dissolved oxygen present in the water and liberate carbon dioxide from the aquatic organisms.

Operculum:

• The flap of skin that can be opened and closed, allowing the movement of water over the gills, is known as the operculum.
• It is made up of bones and helps in protecting the gills from damage.

Therefore, the gills remain protected due to the presence of the operculum.
