Answer:

• Valve between the left atrium and left ventrical.

Step-by-step explanation:

The first part of the heartbeat occurs through the sound of the mitral and tricuspid valves closing. These valves are located between the right upper heart chamber (right atrium) and right lower heart chamber (right ventricle).
