Ventricles are the thick-walled chambers on the ___________ of the heart:

Explanation:
Ventricles are the thick-walled chambers located in the lower portion of the heart. Their muscular walls need to be strong to pump blood under high pressure to the lungs and to the rest of the body, which is why they sit on the bottom half. The thinner-walled atria are up above them, acting as receiving chambers. Being on the outside isn’t correct, since ventricles are internal chambers enclosed within the heart.
