gas exchage takes place through the gills .
sinus venosus > atrium > ventricle > bulbus arteriosus > ventral aorta > afferent branchial artery > gills > efferent branchial artery > aorta
Autotrophic respiration is the respiration produced by the roots of plants.
Cellular respiration need oxygen. This oxygen is supplied by external respiration
The two hearts which supply blood to the gills are called branchial hearts. The more central heart is known as the systemic heart.
No; that is known as "respiration," not "cellular respiration."
No; hermit crabs respiration is provided by branchial appendages.
vagus
Branchial
First branchial arch also known as the mandibular arch is the right answer.
Pila is called as an amphibious mollusc because of its 2 respiratory adaptation, I. e., it can respire in water by by performing branchial respiration with the help of gills or ctenidium ,and live on land by performing pulmonary respiration with the help of pulmonary sac .THANK U 😊

Branchial plexus
Squid use oxygen from seawater for respiration. The seawater enters the mantle through the opening near the head, and passes over the gills. Oxygen diffuses from the water into the blood, and is transported to the gill (or branchial) hearts by a network of many blood vessels.
With introverted branchial appendages of the abdomen called book lungs.
there are three hearts,, in which two are branchial and these pump the blood
Sharks get around without an operculum due to the fact that they instead have branchial flaps. The branchial flaps allow the shark to lay on the sea floor and still "breath" without taking in sand.
prevent food particles from passing through the branchial clefts.
