Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.

Answer 2

Answer:

The heart has four chambers- right and left atrium and right and left ventricle. So deoxygenated blood from the body tissues enters first into right atrium, after which it moves to right ventricle. From the right ventricle, blood goes to lungs where it gets oxygenated. This oxygenated blood moves first to left atrium and then to the left ventricle. Thus, the required answer is left atrium.

Now this concept can be pretty tricky to grasp. Below is a diagrammatic attachment of circulation.
