Answer:
Option (d) all of these is the correct option.
Let's know more in detail about The terms.
Gills:- An operculum protects the fish's gills, which enable them to breathe underwater. Fish exchange carbon dioxide and oxygen with the water beneath their gills through an operculum.
Filament:- A filament is composed of short thread-like structures in the gills that transport ions, water, oxygen, carbon dioxide, acids, and ammonia.
Capillaries:- A large surface area of capillaries allows oxygen and carbon dioxide to exchange within each filament.
All of these:-
As part of their survival mechanism, fish must also breathe oxygen and expel carbon dioxide. Fish use capillaries instead of lungs. A capillary is a tiny, branching organ on the side of the head that contains numerous smaller blood vessels. The operculum is a bony plate that is similar to a comb, except it is shaped like an operculum. By opening its mouth, water flows over its gills and oxygen passes through its capillaries to its blood.
Option (d) all of these is the correct option.
