Answer:

Water enters the mouth and after passing through the buccal cavity, pharynx, and gill pouches, and goes out through the gill slits after bathing the gills.

Explanation:

In scoliosis, the respiration is aquatic, i.e., respiration in water and it breathes using gills borne in a series of gill pouches on either side of the pharynx. Water enters the mouth and after passing through the buccal cavity, pharynx, and gill pouches, and goes out through the gill slits after bathing the gills.

Respiratory Organs:

There are five pairs of lateral gill pouches situated in the lateral walls of the pharynx and are arranged in a series on their side. Each gill pouch is compressed anteroposteriorly and communicates with the cavity of the pharynx through a large internal branchial aperture and with the exterior through a narrow external branchial aperture (commonly called gill slit).

Answer:

Water enters the mouth and after passing through the buccal cavity, pharynx, and gill pouches, and comes out through gill cracks after washing the gills.

Explanation:

In scoliosis, water breathing, that is, breathing in water and breathing using gills held in a series of gill sacs on both sides of the pharynx. Water enters the mouth and after passing through the buccal cavity, pharynx, and gill pouches, and comes out through gill cracks after washing the gills.

Respiratory organs:

There are five pairs of side gill bags located on the side walls of the pharynx and arranged in series on their side. Each gill bag is anteroposteriorly pressed and connects to the pharynx through a large branchial and outer hole through the outer branchial cavity (commonly referred to as the gill slit).
