heart chamber
Blood-holding cardiac space
A heart chamber is one of the enclosed spaces within the heart through which blood flows.
The human heart has four chambers: two upper atria that receive blood and two lower ventricles that pump it out.
The surgeon repaired the damaged heart chamber.
Simpler animals may have fewer chambers.
