Describe the respiratory system in Balanoglysis
Answers
Balanoglossus-Respiratory System. The respiratory apparatus ofBalanoglossus comprises: The branchial sacs that open out through gill-pores. ... The development andarragement of gill-slits is identical with that found in Branchiostoma.The gill-slits are richly lined by cilia, called lateral cilia.

•Balanoglossus lives in burrows in the intertidal sandy areas.
•Its body is long cylindrical.
•In its pharynx 'U' shaped gills are present with increase in its age the number of gills will increase in number.
•Each gill has two lobes.
•These two lobes are separated by tongue bar. This tongue bar is hollow.
It contains coelom.
•Each gill opens into pharynx.
•Near by gills are separated by septa are present.
•Gill is supported by gill bar.
•These gill bars are primary and secondary.
•They are transversely connected by synaptaculae.
•The gills are supplied with blood capillaries.
•These gills open out through gill slits.
•The water from pharynx will enter into the gills.
•Oxygen present in this water will diffuse into the blood of blood capillaries present in the walls of gills like that CO2 from blood will diffuse into the water.
•Thus branchial respiration is carried on in Balanoglossus.
