How many heart champers does osteichthyes?

Osteichthyes, or bony fish, typically have a heart with two chambers: one atrium and one ventricle. This structure allows them to efficiently pump deoxygenated blood to the gills for oxygenation and then circulate oxygenated blood to the rest of the body. While most bony fish share this two-chambered heart design, some species may exhibit variations in their circulatory systems.
