Blood passes from the right atrium to which chamber through the tricuspid valve?

Explanation:
The tricuspid valve sits between the right atrium and the right ventricle, so blood moves from the right atrium into the right ventricle. When the atrium contracts, it pushes blood through this valve into the ventricle, and then the ventricle contracts to pump blood to the lungs, with the valve closing to prevent backflow. The other chambers are connected by different valves (left-sided valves), so they’re not involved here. Thus, the blood passes into the right ventricle.
