The correct answer for the blank is-

Pulmonary artery.

Right ventricles receive deoxygented blood ( from right atrium) when tricuspid valves ( present between right atrium and right ventricle) open.

When ventricles contract, this blood flows from right ventricles to pulmonary artery, which takes it to the lungs.
