Answer 1

Answer:

The heart is divided into four chambers consisting of two atria and two ventricles; the atria receives blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs. The lungs re-oxygenate the blood and send it to the left atrium.
