Which heart chamber receives blood from the pulmonary veins?

right atrium

Explanation:

as  deoxygenated blood enters the vena cava, it flows through the right atrium and right ventricle and leaves by the pulmonary artery and goes to the lung so that the blood can be oxygenated. now the oxygenated blood enters the right atrium via the pulmonary vein and leaves by the aorta.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
