Yes, a human heart has four chambers. The atria are the upper chambers, and the ventricles are the lower chambers.
I believe they are the right ventricle and left atrium. There are 4 chambers and I think these are the 2 lower chambers.

There are many differeces between chondrichthyes and osteichthyes. Chondrichthyes means "cartilaginous fishses", in fact their skeleton is made up of cartilage, while osteichthyes, which means "osseous fishes", have an osseous skeleton, but there are other differences: chondrychthyes have many branchial fessures, different reproduction, lack of swim bladder, and many others.

Osteichthyes is a biological class that includes bony fish. Osteichthyes have skeletons primarily composed of bone tissue. These fish are characterized by their bony skeleton and swim bladder.
Bony fish belong to the Class Sarcopterygii (if lobe-finned) and the Class Actinopterygii (if ray-finned). Coelacanths and lungfish are lobefinned and about all other bony fish are ray-finned. The two classes used to be combined as Class Osteichthyes. There are many superorders and orders in the bony fish classes.
The reproduction among organisms in Osteichthyes varies greatly, but is all sexual reproduction with separate sexes.
